Ditch unused code and features that arent in subject to get supported any near time.

In addition to dead-code removal and other clean-up, bump the required DDX
version from 1.0.0 to 1.1.1. 1.1.1 is over a year and a half old at this point, so it should be pretty widespread. This allows the linecomp_sane field to be eliminated from mga_screen_private_s.

-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
-   The file `configure.in' is used to create `configure' by a program
-called `autoconf'.  You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  You can give `configure'
-initial values for variables by setting them in the environment.  Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
-     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
-     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory.  After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on.  Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
-     CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
-   If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
-     debugging `configure'.
-
-`--help'
-     Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--version'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

   Q) I'm getting a "bad font!" fatal error.
-   A) By default, DOS GLUT compiles with GLUT_IMPORT_LIB, to cope with variable

-      -DGLUT_IMPORT_LIB affects Mesa's `glut.h', your apps must be compiled the

+/**
+ * Public EGL API entrypoints
+ *
+ * Generally, we use the EGLDisplay parameter as a key to lookup the
+ * appropriate device driver handle, then jump though the driver's
+ * dispatch table to handle the function.
+ *
+ * That allows us the option of supporting multiple, simultaneous,
+ * heterogeneous hardware devices in the future.
+ *
+ * The EGLDisplay, EGLConfig, EGLContext and EGLSurface types are
+ * opaque handles implemented with 32-bit unsigned integers.
+ * It's up to the driver function or fallback function to look up the
+ * handle and get an object.
+ * By using opaque handles, we leave open the possibility of having
+ * indirect rendering in the future, like GLX.
+ *
+ *
+ * Notes on naming conventions:
+ *
+ * eglFooBar    - public EGL function
+ * EGL_FOO_BAR  - public EGL token
+ * EGLDatatype  - public EGL datatype
+ *
+ * _eglFooBar   - private EGL function
+ * _EGLDatatype - private EGL datatype, typedef'd struct

+/**
+ * Creates a set of \c __GLcontextModes that a driver will expose.
+ * 
+ * A set of \c __GLcontextModes will be created based on the supplied
+ * parameters.  The number of modes processed will be 2 *
+ * \c num_depth_stencil_bits * \c num_db_modes.
+ * 
+ * For the most part, data is just copied from \c depth_bits, \c stencil_bits,
+ * \c db_modes, and \c visType into each \c __GLcontextModes element.
+ * However, the meanings of \c fb_format and \c fb_type require further
+ * explanation.  The \c fb_format specifies which color components are in
+ * each pixel and what the default order is.  For example, \c GL_RGB specifies
+ * that red, green, blue are available and red is in the "most significant"
+ * position and blue is in the "least significant".  The \c fb_type specifies
+ * the bit sizes of each component and the actual ordering.  For example, if
+ * \c GL_UNSIGNED_SHORT_5_6_5_REV is specified with \c GL_RGB, bits [15:11]
+ * are the blue value, bits [10:5] are the green value, and bits [4:0] are
+ * the red value.
+ * 
+ * One sublte issue is the combination of \c GL_RGB  or \c GL_BGR and either
+ * of the \c GL_UNSIGNED_INT_8_8_8_8 modes.  The resulting mask values in the
+ * \c __GLcontextModes structure is \b identical to the \c GL_RGBA or
+ * \c GL_BGRA case, except the \c alphaMask is zero.  This means that, as
+ * far as this routine is concerned, \c GL_RGB with \c GL_UNSIGNED_INT_8_8_8_8
+ * still uses 32-bits.
+ *
+ * If in doubt, look at the tables used in the function.
+ * 
+ * \param ptr_to_modes  Pointer to a pointer to a linked list of
+ *                      \c __GLcontextModes.  Upon completion, a pointer to
+ *                      the next element to be process will be stored here.
+ *                      If the function fails and returns \c GL_FALSE, this
+ *                      value will be unmodified, but some elements in the
+ *                      linked list may be modified.
+ * \param fb_format     Format of the framebuffer.  Currently only \c GL_RGB,
+ *                      \c GL_RGBA, \c GL_BGR, and \c GL_BGRA are supported.
+ * \param fb_type       Type of the pixels in the framebuffer.  Currently only
+ *                      \c GL_UNSIGNED_SHORT_5_6_5, 
+ *                      \c GL_UNSIGNED_SHORT_5_6_5_REV,
+ *                      \c GL_UNSIGNED_INT_8_8_8_8, and
+ *                      \c GL_UNSIGNED_INT_8_8_8_8_REV are supported.
+ * \param depth_bits    Array of depth buffer sizes to be exposed.
+ * \param stencil_bits  Array of stencil buffer sizes to be exposed.
+ * \param num_depth_stencil_bits  Number of entries in both \c depth_bits and
+ *                      \c stencil_bits.
+ * \param db_modes      Array of buffer swap modes.  If an element has a
+ *                      value of \c GLX_NONE, then it represents a
+ *                      single-buffered mode.  Other valid values are
+ *                      \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and
+ *                      \c GLX_SWAP_UNDEFINED_OML.  See the
+ *                      GLX_OML_swap_method extension spec for more details.
+ * \param num_db_modes  Number of entries in \c db_modes.
+ * \param visType       GLX visual type.  Usually either \c GLX_TRUE_COLOR or
+ *                      \c GLX_DIRECT_COLOR.
+ * 
+ * \returns
+ * \c GL_TRUE on success or \c GL_FALSE on failure.  Currently the only
+ * cause of failure is a bad parameter (i.e., unsupported \c fb_format or
+ * \c fb_type).
+ * 
+ * \todo
+ * There is currently no way to support packed RGB modes (i.e., modes with
+ * exactly 3 bytes per pixel) or floating-point modes.  This could probably
+ * be done by creating some new, private enums with clever names likes
+ * \c GL_UNSIGNED_3BYTE_8_8_8, \c GL_4FLOAT_32_32_32_32, 
+ * \c GL_4HALF_16_16_16_16, etc.  We can cross that bridge when we come to it.
