This reverts commit bc4148933670cea024cf7525b58bfa673898ec75. The reason this was causing problems for Clutter is that it defines COGL_ENABLE_EXPERIMENTAL_2_0_API which is meant to cause the Cogl headers not to declare the deprecated API. The reverted patch moved some additional clipping API to a deprecated header which was previously being used by Clutter. Clutter was still successfully compiling but with some warnings for the missing function declarations. However when the binary is run the clipping would get completely messed up because it would assume all of the arguments to the functions are integers instead of floats and the wrong values would be passed. Clutter now has commit to make it use the 2.0 API instead of the deprecated functions so the revert is no longer necessary. https://git.gnome.org/browse/clutter/commit?id=705640367a5c2ae21405806bfa Reviewed-by: Robert Bragg <robert@linux.intel.com>
