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.

7293fd517e glyph cache: Stop storing driver and render

d81cf5a443 rendernodeparser: Handle Cairo being stupid 
Cairo writes to finished streams, so we have to make sure to keep the
stream around to allow it to do that.

05ca772631 GskTransform: Ignore identity transforms 
We often end up with e.g. a scale of 1 or a translation by 0/0. Ignore
those transforms since they don't do anything.

3c6c07e94d gl: Avoid a memdup in glyph upload 
We don't need to dup the memory here if we
set up the image surface properly. This won't
matter for most glyphs, but some of them can
be big.

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.

5a0c8805fc transform: Coalesce similar transforms 
If somebody does a transform like
  scale(5) scale(10) translate(1,1) translate(5,0)
store it instead as
  scale(50) translate(6,1)
This way, less memory is consumed and transforms are easier to read.

In particular, this simplifies the typical transforms we do in GTK,
which are just one translation after another.

1e0c0c0ba7 rendernodeparser: Parse cairo script 
Use cairo-script-interpreter to parse the scripts that generate cairo
nodes.

This requires libcairoscriptinterpreter.so to work properly, but if
it isn't found we disable this (unimportant for normal functioning)
code and just emits a parser warning.
The testsuite requires it however or it will fail.

A new test is included that tests all of this.
