/**
|
|
* 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;
|
|
* 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.
