32 * The GL texture image functions in teximage.c basically just do
33 * error checking and data structure allocation. They in turn call
34 * device driver functions which actually copy/convert/store the user's
35 * texture image data.
36 *
37 * However, most device drivers will be able to use the fallback functions
38 * in this file. That is, most drivers will have the following bit of
39 * code:
40 * ctx->Driver.TexImage = _mesa_store_teximage;
41 * ctx->Driver.TexSubImage = _mesa_store_texsubimage;
42 * etc...
43 *
44 * Texture image processing is actually kind of complicated. We have to do:
45 * Format/type conversions
46 * pixel unpacking
47 * pixel transfer (scale, bais, lookup, etc)
48 *
49 * These functions can handle most everything, including processing full
50 * images and sub-images.
