9d3aa2cfce gsk: Avoid compiler warnings without assertions 
Disabling assertions was provoking some unused variable
warnings from the compiler. Avoid these.

900a4e4d31 gsk: Move shader resources 
Move the resources of each renderer to its subdirectory.
We've previously done that for the ngl renderer, but it
is better to be consistent and do it for all the renderers.

ee63b84b6a gsk: Rename resource paths 
Make the shaders of the gl renderer live under
/org/gtk/libgsk/gl. This is purely cosmetic.

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

0d0bdaa02e gsk: Fix a thinko

34ffdc6e3f gl: Fix implicit leaking of shader object 
According to OpenGL spec, a shader object will only be flagged
for deletion unless it has been detached; when a program object
is deleted, those shader objects attached to it will be detached
but not deleted unless they have already been flagged for deletion.

So we shall detach a shader object before it is deleted, and delete
it before the program object is deleted best.

6883c2214b gl: specify attribute locations for vUv and aPosition 
These positions are not guaranteed to be in a specific order when linked
into the final GPU program. They need to be specified so that our code
in gskglrenderer.c can use known positions for them to match up with
our GskQuadVertex.

This fixes the GL renderer on macOS's OpenGL shader compiler.

c907ad83b0 glrenderer: Emit more useful error messages 
Catch the error when it happens, so that we can emit a specific and more
helpful error message.

Also verify that all branches in the code now do indeed set a proper
GError when they fail, so that the final catch-all is no longer needed.
Instead, assert that the error is set so that we catch future code
additions early that do not set the GError.

12a9164414 gsk: use glFrameBufferTexture2D and release texture 
glFrameBufferTexture maps to all faces of a cube and that is not needed
here. Additionally, texture_id is not deleted after we use the additional
flipped texture, but should be.
