In commit 091eb15b69, Jordan changed get_temp_image_type() to use
_mesa_get_format_datatype() instead of returning GL_FLOAT. That has
several possible return values: GL_FLOAT, GL_INT, GL_UNSIGNED_INT,
GL_SIGNED_NORMALIZED, and GL_UNSIGNED_NORMALIZED.
We do want to use GL_INT/GL_UNSIGNED_INT for integer formats. However,
we want to continue using GL_FLOAT for the normalized fixed-point types.
There isn't any code in pack.c to handle GL_(UN)SIGNED_NORMALIZED.
Fixes oglconform's fboarb advanced.blit.copypix, which was regressed by
commit 091eb15b69.
NOTE: This is a candidate for the 9.0 branch.
