259bbdcb09 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.

e0803f039f gl: Fix glyph cache aging 
The logic here seems faulty. We want to keep
a timestamp that tells us when the glyph was
last used, so always update the timestamp.

And whenever we use a glyph, it turns 'young'
again, so remove it from the old pixels
accounting.

The (MAX_AGE, MAX_AGE+CHECK_INTERVAL) interval
is only relevant to prevent us from turning
a cached glyph old more than once, and that
is already taken care of.

upside-down vertex data for everything.

bd113aa85c transform: Redo querying API 
Make the API expect a tranform of the proper category instead of
doing the check ourselves and returning TRUE/FALSE.

The benefit is that the mai use case is switch (transform->category)

TRUE/FALSE.

a872c41f79 glglyphcache: Fix dropping caches unnecessarily 
The first set of glyphs is created with a timestamp of 1. Later we
subtract the glyph timestamp from the cache timestamp, meaning we end up
with numbers ending in 9, e.g. 59. Now unfortunately !(60 <= 59), so we
do not end up incrasing the old_pixels count of the cache. Later we then
call lookup() and DEcrease the old_pixels count, which makes the
unsigned int wrap and cause a huge old_pixels value, which causes us to
drop the cache.

41a922928e gl renderer: Render GL textures upside down 
These come from an FBO so we need to flip the texture coords on the y
axis, just like we do everywhere else.

c56419818f gsk: make logging per-renderer 
Add a setter for per-renderer debug flags, and use
them where possible. Some places don't have easy access
to a renderer, so this is not complete.
Also, use g_message instead of g_print throughout.
