91bbe6ef95 gl renderer: Sync gpu and cpu default alpha value 
Otherwise we might end up not passing the new value to the GPU.

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
texture drawing ops.

This fixes the stack cube rotation transition to at least look somewhat
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().

7931ab5f33 gl renderer: Change shadow cache eviction strategy 
Since we can do partial redraws, dropping every shadow that's been
unused for one frame happens too fast. This is also a problem when a
shadow gets drawn on a texture for a few frames.

416a4cf5ea gl renderer: Ignore nodes with nan bounds 
This can happen for certain transform nodes. The transform node's
child's bounds are fine, but the transform node bounds are all nan.
Just ignore those bounds since we can't meaningfully render them anyway.

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

texture because of it.

12378f0afa gl renderer: Expand matrix metadata extraction 
Instead of getting the translation x/y everytime we use the modelview,
get it once, when extracting the metadata. Do the same with the scale.
And save if the matrix is "simple" at all, i.e. if it only consists of a
translation and/or scale. This will be helpful later when we start
drawing transformed nodes on textures.

d15df65a9d gl renderer: Save some matrix multiplications 
We do this for every single node, which is a little costly, especially

translation matrix and if so, don't do a full matrix multiplication per
node.

a865621519 gdk: Move begin/end_frame() functions 
As they require a draw context and the draw context is already bound to
the surface, it makes much more sense and reduces abiguity by moving
these APIs to the draw context.

As a side effect, we simplify GdkSurface APIs to a point where
GdkSurface now does not concern itself with drawing anymore at all,
apart from being the object that creates draw contexts.
