[Mesa-dev] [PATCH 4/5] r100: Use _mesa_get_format_base_format in radeon_update_wrapper

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

The wrapper is for a renderbuffer around a texture.  Textures can have
formats (e.g., 3) that aren't valide for API generated renderbuffers.
_mesa_base_fbo_format will return 0, but _mesa_get_format_base_format
will return the base format of RGB.

Fixes a crashes in piglit tests fbo-alphatest-formats (all subtests
pass) and fbo-colormask-formats (some subtests pass, some fail).
