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 
Pass the glyph position into the glyph caching functions,
not just the glyph index. This allows us to cache different
images for different subpixel positions.

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.

Fixes part of #2046

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.

aa922f0779 gl renderer: Pass correct matrix category when rendering offscreen 
We can't just pretend we have an identity matrix when we are actually
scaling. This fixes the node editor sometimes not drawing things when
rendering to a texture. We were mistakenly discaring render nodes
because the bounds transformation was wrong.

63267a2f70 gl renderer: Render fallback nodes upside down 
We stuff both gl-drawn and cairo-drawn textures into the same cache, so
we can't really assume that we need to draw any of them flipped or not.
Fix this by drawing fallback stuff upside down and then using
upside-down vertex data for everything.

1a7c280ebb gl renderer: bind the texture framebuffer before rendering

e13d242320 gl renderer: Keep op builder around

cc878ec00f gl renderer: begin/end_frame around do_render 
This fixes rendering to a texture on intel hardware. The glClear calls
would throw a GL_FRAMEBUFFER_INCOMPLETE error here, because the
gsk_gl_driver_begin_frame() call in do_render() reset the framebuffer
object in use.

0245ac2106 gl renderer: Apply transform only for final texture drawing 
We don't want the new transform while drawing things on a texture.
Instead, only apply the new transform matrix when adding the final

better.

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)
statements and in those we know the category and don't need to check
TRUE/FALSE.

Using the wrong matrix will now cause a g_warning().

416a4cf5ea gl renderer: Ignore nodes with nan bounds

6a4bf2b993 gsk: Remove offset nodes 
They were a neat idea while they lasted. But now, it's time for

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