Robert Bragg 34658ea057 generalize driver description and selection ... This adds a table of driver descriptions to cogl-renderer.c in order of preference and when choosing what driver to use we now iterate the table instead of repeating boilerplate checks. For handling the "default driver" that can be specified when building cogl and handling driver overrides there is a foreach_driver_description() that will make sure to iterate the default driver first or if an override has been set then nothing but the override will be considered. This patch introduces some driver flags that let us broadly categorize what kind of GL driver we are currently running on. Since there are numerous OpenGL apis with different broad feature sets and new apis may be introduced in the future by Khronos then we should tend to avoid using the driver id to do runtime feature checking. These flags provide a more stable quantity for broad feature checks.
