* Intro to using the VGA/Mesa interface
*
* 1. #include the <vga.h> file
* 2. Call vga_init() to initialize the SVGA library.
* 3. Call vga_setmode() to specify the screen size and color depth.
* 4. Call SVGAMesaCreateContext() to setup a Mesa context. If using 8-bit
* color Mesa assumes color index mode, if using 16-bit or deeper color
* Mesa assumes RGB mode.
* 5. Call SVGAMesaMakeCurrent() to activate the Mesa context.
* 6. You can now use the Mesa API functions.
* 7. Before exiting, call SVGAMesaDestroyContext() then vga_setmode(TEXT)
* to restore the original text screen.
*
* Notes
* 1. You must run your executable as root (or use the set UID-bit) because
* the SVGA library requires it.
* 2. The SVGA driver is not fully implemented yet. See svgamesa.c for what
* has to be done yet.

/* Win32 has an annoying issue where there are multiple C run-time
libraries (CRTs). If the executable is linked with a different CRT
from the GLUT DLL, the GLUT DLL will not share the same CRT static
data seen by the executable. In particular, atexit callbacks registered
in the executable will not be called if GLUT calls its (different)
exit routine). GLUT is typically built with the
"/MD" option (the CRT with multithreading DLL support), but the Visual
C++ linker default is "/ML" (the single threaded CRT).
One workaround to this issue is requiring users to always link with
the same CRT as GLUT is compiled with. That requires users supply a
non-standard option. GLUT 3.7 has its own built-in workaround where
the executable's "exit" function pointer is covertly passed to GLUT.
GLUT then calls the executable's exit function pointer to ensure that
any "atexit" calls registered by the application are called if GLUT
needs to exit.
Note that the __glut*WithExit routines should NEVER be called directly.
To avoid the atexit workaround, #define GLUT_DISABLE_ATEXIT_HACK. */

* Fix up alpha buffer handling for Windows.
* - add two new Pixel Format Descriptors that do not have alpha bits to
* mirror the two that do.
* - add logic to wglChoosePixelFormat to match PFD's with respect to alpha.
* - Create/clear software alpha buffer as required.
* Now a wgl or GLUT program can control the creation of a software alpha

/* Sample Usage:
In addition to the usual X calls to select a visual, create a colormap
and create a window, you must do the following to use the X/Mesa interface:
1. Call XMesaCreateVisual() to make an XMesaVisual from an XVisualInfo.
2. Call XMesaCreateContext() to create an X/Mesa rendering context, given
the XMesaVisual.
3. Call XMesaCreateWindowBuffer() to create an XMesaBuffer from an X window
and XMesaVisual.
4. Call XMesaMakeCurrent() to bind the XMesaBuffer to an XMesaContext and
to make the context the current one.
5. Make gl* calls to render your graphics.
6. Use XMesaSwapBuffers() when double buffering to swap front/back buffers.
7. Before the X window is destroyed, call XMesaDestroyBuffer().
8. Before exiting, call XMesaDestroyVisual and XMesaDestroyContext.

* Mesa Off-Screen rendering interface.
*
* This is an operating system and window system independent interface to
* Mesa which allows one to render images into a client-supplied buffer in
* main memory. Such images may manipulated or saved in whatever way the
* client wants.
*
* These are the API functions:
* OSMesaCreateContext - create a new Off-Screen Mesa rendering context
* OSMesaMakeCurrent - bind an OSMesaContext to a client's image buffer
* and make the specified context the current one.
* OSMesaDestroyContext - destroy an OSMesaContext
* OSMesaGetCurrentContext - return thread's current context ID
* OSMesaPixelStore - controls how pixels are stored in image buffer
* OSMesaGetIntegerv - return OSMesa state parameters
*
*
* The limits on the width and height of an image buffer are MAX_WIDTH and
* MAX_HEIGHT as defined in Mesa/src/config.h. Defaults are 1280 and 1024.
* You can increase them as needed but beware that many temporary arrays in
* Mesa are dimensioned by MAX_WIDTH or MAX_HEIGHT.

* The GL texture image functions in teximage.c basically just do
* error checking and data structure allocation. They in turn call
* device driver functions which actually copy/convert/store the user's
* texture image data.
*
* However, most device drivers will be able to use the fallback functions
* in this file. That is, most drivers will have the following bit of
* code:
* ctx->Driver.TexImage1D = _mesa_store_teximage1d;
* ctx->Driver.TexImage2D = _mesa_store_teximage2d;
* ctx->Driver.TexImage3D = _mesa_store_teximage3d;
* etc...
*
* Texture image processing is actually kind of complicated. We have to do:
* Format/type conversions
* pixel unpacking
* pixel transfer (scale, bais, lookup, convolution!, etc)
*
* These functions can handle most everything, including processing full
* images and sub-images.

* This function is used to transfer the user's image data into a texture
* image buffer. We handle both full texture images and subtexture images.
* We also take care of all image transfer operations here, including
* convolution, scale/bias, colortables, etc.
*
* The destination texel type is always GLchan.
* The destination texel format is one of the 6 basic types.
*
* A hardware driver may use this as a helper routine to unpack and
* apply pixel transfer ops into a temporary image buffer. Then,
* convert the temporary image into the special hardware format.
*
* Input:
* dimensions - 1, 2, or 3
* texDestFormat - GL_LUMINANCE, GL_INTENSITY, GL_LUMINANCE_ALPHA, GL_ALPHA,
* GL_RGB or GL_RGBA (the destination format)
* texDestAddr - destination image address
* srcWidth, srcHeight, srcDepth - size (in pixels) of src and dest images
* dstXoffset, dstYoffset, dstZoffset - position to store the image within
* the destination 3D texture
* dstRowStride, dstImageStride - dest image strides in bytes
* srcFormat - source image format (GL_ALPHA, GL_RED, GL_RGB, etc)
* srcType - GL_UNSIGNED_BYTE, GL_UNSIGNED_SHORT_5_6_5, GL_FLOAT, etc
* srcPacking - describes packing of incoming image.
* transferOps - mask of pixel transfer operations

* CONVERT_DIRECT - if defined, just memcpy texels from src to dest
* SRC_TEXEL_BYTES - bytes per source texel

Thoughts on vertex program optimization:
The obvious thing to do is to compile the vertex program into X86/SSE/3DNow!
assembly code. That will probably be a lot of work.
Another approach might be to replace the vp_instruction->Opcode field with
a pointer to a specialized C function which executes the instruction.
In particular we can write functions which skip swizzling, negating,
masking, relative addressing, etc. when they're not needed.
For example:
void simple_add( struct vp_instruction *inst )
{
GLfloat *sum = machine->Registers[inst->DstReg.Register];
GLfloat *a = machine->Registers[inst->SrcReg[0].Register];
GLfloat *b = machine->Registers[inst->SrcReg[1].Register];
sum[0] = a[0] + b[0];
sum[1] = a[1] + b[1];
sum[2] = a[2] + b[2];
sum[3] = a[3] + b[3];
}
*/
/*
KW:
A first step would be to 'vectorize' the programs in the same way as
the normal transformation code in the tnl module. Thus each opcode
takes zero or more input vectors (registers) and produces one or more
output vectors.
These operations would intially be coded in C, with machine-specific
assembly following, as is currently the case for matrix
transformations in the math/ directory. The preprocessing scheme for
selecting simpler operations Brian describes above would also work
here.
This should give reasonable performance without excessive effort.

/*
* This file manages the OpenGL API dispatch layer.
* The dispatch table (struct _glapi_table) is basically just a list
* of function pointers.
* There are functions to set/get the current dispatch table for the
* current thread and to manage registration/dispatch of dynamically
* added extension functions.
*
* It's intended that this file and the other glapi*.[ch] files are
* flexible enough to be reused in several places: XFree86, DRI-
* based libGL.so, and perhaps the SGI SI.
*
* NOTE: There are no dependencies on Mesa in this code.
*
* Versions (API changes):
* 2000/02/23 - original version for Mesa 3.3 and XFree86 4.0
* 2001/01/16 - added dispatch override feature for Mesa 3.5
* 2002/06/28 - added _glapi_set_warning_func(), Mesa 4.1.
* 2002/10/01 - _glapi_get_proc_address() will now generate new entrypoints
* itself (using offset ~0). _glapi_add_entrypoint() can be
* called afterward and it'll fill in the correct dispatch
* offset. This allows DRI libGL to avoid probing for DRI
* drivers! No changes to the public glapi interface.

* Imports are services which the device driver or window system or

* will call these functions in order to do memory allocation, simple I/O,
* etc.
*
* Some drivers will want to override/replace this file with something
* specialized, but that'll be rare.
*
* Eventually, I want to move roll the glheader.h file into this.
*
* The OpenGL SI's __GLimports structure allows per-context specification of
* replacements for the standard C lib functions. In practice that's probably
* never needed; compile-time replacements are far more likely.
*
* The _mesa_foo() functions defined here don't in general take a context
* parameter. I guess we can change that someday, if need be.
* So for now, the __GLimports stuff really isn't used.

* This file is a template which generates the OpenGL API entry point
* functions. It should be included by a .c file which first defines
* the following macros:
* KEYWORD1 - usually nothing, but might be __declspec(dllexport) on Win32
* KEYWORD2 - usually nothing, but might be __stdcall on Win32
* NAME(n) - builds the final function name (usually add "gl" prefix)
* DISPATCH(func, args, msg) - code to do dispatch of named function.
* msg is a printf-style debug message.
* RETURN_DISPATCH(func, args, msg) - code to do dispatch with a return value
*
* Here's an example which generates the usual OpenGL functions:
* #define KEYWORD1
* #define KEYWORD2
* #define NAME(func) gl##func
* #define DISPATCH(func, args, msg) \
* struct _glapi_table *dispatch = CurrentDispatch; \
* (*dispatch->func) args
* #define RETURN DISPATCH(func, args, msg) \
* struct _glapi_table *dispatch = CurrentDispatch; \
* return (*dispatch->func) args
