50554bb92b renderers: Handle large viewports
When large viewports are passed to gsk_renderer_render_texture(), don't
fail (or even return NULL).

Instead, draw multiple tiles and assemble them into a memory texture.

Tests added to the testsuite for this.

fd6b3ef5a0 gl: Linear gradients don't support 3d transforms
Add another helper similar to the one for transforms, but that only
works on 2d transforms.

144f727d5a Rename ngl to gl
We have only one gl renderer now, and it is
a bit odd for it not be called gl.

46bb160923 testuite: Add opacity-overdraw test
Tests that overdrawing of content inside an opacity node happens before
the opacity is applied.

This is broken in the GL renderer and causes the opacity.ui reftest to
fail.

so don't use the test with the gl renderer, until it is

b5df1299ec gsk: Add another test
Compare clipped repeat nodes. Must skip cairo here

Also skip the gl renderer, since it hasn't been fixed

2a38cecd33 gsk: add OpenGL based GskNglRenderer
The primary goal here was to cleanup the current GL renderer to make
maintenance easier going forward. Furthermore, it tracks state to allow
us to implement more advanced renderer features going forward.

Reordering

This renderer will reorder batches by render target to reduce the number
of times render targets are changed.

In the future, we could also reorder by program within the render target
if we can determine that vertices do not overlap.

Uniform Snapshots

To allow for reordering of batches all uniforms need to be tracked for
the programs. This allows us to create the full uniform state when the
batch has been moved into a new position.

Some care was taken as it can be performance sensitive.

Attachment Snapshots

Similar to uniform snapshots, we need to know all of the texture
attachments so that we can rebind them when necessary.

Render Jobs

To help isolate the process of creating GL commands from the renderer
abstraction a render job abstraction was added. This could be extended
in the future if we decided to do tiling.

Command Queue

Render jobs create batches using the command queue. The command queue
will snapshot uniform and attachment state so that it can reorder
batches right before executing them.

Currently, the only reordering done is to ensure that we only visit
each render target once. We could extend this by tracking vertices,
attachments, and others.

This code currently uses an inline array helper to reduce overhead
from GArray which was showing up on profiles. It could be changed to
use GdkArray without too much work, but had roughly double the
instructions. Cycle counts have not yet been determined.

GLSL Programs

This was simplified to use XMACROS so that we can just extend one file
(gskglprograms.defs) instead of multiple places. The programs are added
as fields in the driver for easy access.

Driver

The driver manages textures, render targets, access to atlases,
programs, and more. There is one driver per display, by using the
shared GL context.

Some work could be done here to batch uploads so that we make fewer
calls to upload when sending icon theme data to the GPU. We'd need
to keep a copy of the atlas data for such purposes.

1c6cf7a3b6 reftests: Share reftest-compare.[ch] between GSK and GTK tests
The only non-whitespace difference is that the copy in GSK does not
set the symbol's visibility.

dff2aa20ff gl: Fixed clipped offscreen rendering
When we are rendering a texture node to an offscreen,
and we have a clip, we must force the offscreen rendering.
Otherwise, the code will notice: Hey, it already is a texture
node, so no need to render it to a texture again. But when
clipping is involved, that is exactly what we want to do.

Testcase included.

Fixes: #3651

0af6630521 a11y: Consolidate accessibility environment variables
Use a single environment variable for everything:

 - select the ATContext implementation
 - select the test ATContext
 - disable ATContext entirely

We use the same pattern as GSK_RENDERER, GTK_DEBUG, etc.

The documentation needs to be updated to include the environment
variable.

cbb0ca4902 testsuite: Tell meson we use TAP
This makes meson actually parse the individual test
results. Most of the time, it does not make a difference,
but one case where it does is when all the individual

a3be0ec5f0 Don't use xsettings or xft defaults in testsuite
This adds a GDK_DEBUG=default-settings flag which disables reads
from xsettings and Xft resources, and enables this for the testsuite.

This is one less way to get different testresults depending on the
environment. In particular, it was failing the css tests for me
due to getting the wrong font size because i have a different dpi.
