-/**
- * \file texutil_tmp.h
- * Texture conversion templates.
- *
- * \author Gareth Hughes
- *
- * For 2D and 3D texture images, we generate functions for
- * - conversion without pixel unpacking and standard stride
- * - conversion without pixel unpacking and non-standard stride
- * - conversion with pixel unpacking and standard stride
- * - conversion with pixel unpacking and non-standard stride
- *
- * Macros which need to be defined before including this file:
- * - \c TAG(x) - the function name wrapper
- * - \c DST_TYPE - the destination texel data type (GLuint, GLushort, etc)
- * - \c DST_TEXELS_PER_DWORD - number of destination texels that'll fit in 4 bytes
- * - \c CONVERT_TEXEL - code to convert from source to destination texel
- * - \c CONVER_TEXEL_DWORD - if multiple texels fit in 4 bytes, this macros
- * will convert/store multiple texels at once
- * - \c CONVERT_DIRECT - if defined, just memcpy texels from source to destination
- * - \c SRC_TEXEL_BYTES - bytes per source texel
- * - \c PRESERVE_DST_TYPE - if defined, don't undefined these macros at end
- *
- * \sa convert_func.
