This improves the OpenGL ES support to extend it to version 3.0. A number of new features are available in glesv3 including creation of multi-sampled renderbuffers. These renderbuffers can be blitted to single sample textures (but not the other way around). Other features such as PBO for image uploading, are left as followon work. For this preliminary implementation, glesv3 backends always create renderbuffers, which can be set as single sample or multisample. The renderbuffer's content is blitted to the texture only when used as a source or a mask. Images uploaded to a texture stay there until the surface is used as a rendering target, at which point its painted to the renderbuffer. This patch is heavily based off of Henry Song's initial GLESv3 patch 6f7f3795 from his cairogles fork of Cairo, and incorporates subsequent fixes and pertinent refactorings from his trunk and review feedback from Uli. This implements the *functional* support for glesv3, excluding the various optimization work to utilize its features. Rendering and performance should not be expected to improve notably from pure glesv2. As the GL backend for Cairo remains "experimental", these changes should likewise be considered as such.

This directory provides code that is common to both of cairo's tests suites: * The test suite for correctness in test/ * The test suite for performance in perf/ We call it boilerplate as it consists primarily of the boilerplate code necessary for initializing a backend in order to create a surface for that backend. The code here just might be useful for someone looking to get started writing cairo code to use a particular backend, (but there are no promises that the boilerplate code found here for any particular backend is exemplary).
