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.TexImage1D = _mesa_store_teximage1d;
41 * ctx->Driver.TexImage2D = _mesa_store_teximage2d;
42 * ctx->Driver.TexImage3D = _mesa_store_teximage3d;
43 * etc...
44 *
45 * Texture image processing is actually kind of complicated. We have to do:
46 * Format/type conversions
47 * pixel unpacking
48 * pixel transfer (scale, bais, lookup, etc)
49 *
50 * These functions can handle most everything, including processing full
51 * images and sub-images.
