gl renderer: Upload GL_RGBA texture data in GLES
...
Colored icons are still broken this way, but at least they show up and
text works.

gl: Speed up icon cache lookups
...
Use gdk_texture_set_render_data to avoid
hash table lookups when we can.

gl: Slightly rework the icon cache api
...
Return a pointer to the IconData struct. This is
closer to the glyph cache api, and will allow us
to add similar shortcuts. For now, just store
texture coords in the form we need, avoiding
converting them over and over.

gl: Increate the cache check frequency
...
Otherwise, we spread the cache over more atlases
than necessary, increasing the amount of texture
changes in each frame.

gl: Improve debug spew for caches
...
Dump similar information for both caches,
and correct the unused percentage for
the atlases.

gl: Make icon cache work like glyph cache
...
Replace timestamp tracking with an accessed bit
here too, to keep the glyph and icon cache code
similar.

gl: Handle row stride for icon cache upload
...
Same as the previous commit: Downloading a texture
may in theory give us data with a stride, so handle
that.

gl: Do less work to maintain caches
...
Remember which atlases were removed, and only
check those when looking for icons or glyphs
to remove. For most frames, we don't have to
check at all since no atlases were removed.

Avoid expensive padding, and just upload the
image in several slices.

iconcache: ref textures
...
We can't just assume that the pointer we'se using as a cache key will
stay unique forever. The texture might be freed, and a later allocated
texture might have the same addres now, causing the cache to return
incorrect results.

Share glyph and icon caches
...
Use the same texture atlases to back both
the glyph and icon caches, and unify their
sizes and management. Store big glyphs
in separate textures, so all atlases have
the same size. Tweak some of the eviction
parameters.
We share the caches across all GL contexts
on a display, unless the GSK_NO_SHARED_CACHES
env var is set.
