- * 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, etc)

- *

- * These functions can handle most everything, including processing full

- * images and sub-images.
