Since e07d0fc7441 the COGL_DRIVER environment variable was able to
override the application's driver selection. This doesn't seem like a
good idea because if the application is specifying a driver explicitly
then presumably it can not work with any other driver. This patch
changes it so that if a driver is selected in the configuration and by
the application then they must match, otherwise it will fail with a
CoglError.

Only COGL_RENDERER_CONSTRAINT_SUPPORTS_COGL_GLES2 affects the driver
selection and all of the the other constraints are only relevant to
the winsys selection. However Cogl was trying to apply all of the
constraints to the driver selection which meant that if any other
constraint was specified then it would always fail. This patch makes
the driver selection filter out all other constraints based on a mask
defined in cogl-renderer-private.h.

Currently it's only possible to set an onscreen template on a
CoglDisplay by passing a template to cogl_display_new(). For
applications that want to deal with fallbacks then they may want to
replace the onscreen template so this adds a
cogl_display_set_onscreen_template() function.

and instead requires you to use the DEPTH_STENCIL_ATTACHMENT whenever

This adds a COGL_DRIVER_WEBGL enum and a new driver description for

driver flag and a HAVE_COGL_WEBGL define which we can start to use to
handle special cases where webgl differs from gles2.

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.

Each level in the tower is initialized by binding the texture for that
level to an offscreen framebuffer and rendering the previous level as a
textured rectangle. The problem was that we were blending the previous
level with undefined data so argb32 windows with transparencies would
result in artefacts. This makes sure to disable blending when drawing
the textured rectangle.
The data->fill_primitive member is meant to be generated on demand in
an accessor function. However when using it for clipping the code was
trying to directly use it without calling the accessor so it would
crash if nothing else caused the primitive to be generated. This was
making the texture-fbo test in Clutter crash.
