[Piglit] [PATCH 09/14] util: Factor piglit_framework_fbo code into its own file

Chad Versace chad.versace at linux.intel.com
Mon May 21 23:15:17 PDT 2012


This moves the piglit_framework_fbo code from piglit-framework.c to
piglit-framework-fbo.c.

Currently the piglit_framework_fbo code is only implemented for GLX. The
next commit adds an implementation atop Waffle. The increase in code size
and #ifdef complexity warrants moving it to its own file.
