[Cogl] [PATCH 0/3] Improving webgl support

[Robert Bragg]

From: Robert Bragg <robert at linux.intel.com>

As I've started playing with building Rig's rendering engine using Emscripten
I came across some issues with how we allocate framebuffer due to webgl requiring
the use of a DEPTH_STENCIL_ATTACHMENT point instead of separate depth and stencil
attachments. This adds a new webgl driver to Cogl and makes some improvements
to how we condition various things in Cogl based on broad GL feature sets.

regards,
- Robert

Robert Bragg (3):
  generalize driver description and selection
  Adds "webgl" driver
  webgl: use DEPTH_STENCIL_ATTACHMENT
