251bf45cf2 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.

b576aef2b1 Revert "gl: Simplify glyph cache rendering" 
This reverts commit 7a3eaad193.

The reason we want to keep using pango here
is that we get hex boxes and similar drawing
features that way.

d276d2629a gl: Glyph cache fixes 
Pass the full location to the glyph cache lookup,
and use the same rounding as cairo does. This makes
the output much closer to the cairo renderer.

5dd8801ee5 gl: implement subpixel positioning

7a3eaad193 gl: Simplify glyph cache rendering 
We are currently using a weird mix of pango and cairo,
but there is no need for us to go through a pango
renderer here; we can just use cairo directly.

2c38b71ca5 glyph cache: Upload large glyphs in lookup () directly 
Instead of relying on a texture id of 0, which can happen for other
reasons, e.g. when the glyph is being scaled too small.

1c93bef0d5 glyph cache: check glyphs for scaled size 
We can't rely on just the ink_rect, since that might be without the

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

the same size. Tweak some of the eviction
parameters.

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.

GSK_MATRIX_CATEGORY_2D_TRANSLATE are the exact replacement.

Renderers have not been adapted for this purpose, so they (continue to)
run slow paths.

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.

359bc7695c build: Reintroduce warning flags from autotools 
Some of the flags got lost in the meson transition or were demoted from
error flags to warning flags.
This commit reintroduces them.

It also includes fixes for the code that had warnings with those flags.
The big one being -Wshadow.

59bf76dce1 gl renderer: Force blur shadow node children offscreen 
This broke the overlay blur demoe when resizing the window to a size
that would completely move the image below a button, causing the
GtkSnapshot code to remove the clip node below the blur node.

1d3aa9207c gl renderer: Add a clip stack 
So we can check that the currently set clip is the first one and now
intersect with it. This first clip is always the entire viewport or the
entire render_area and we don't want to end up drawing things to a
texture because of it.
