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