8c61038b9f gl renderer: print fragment shader info 
It was logged twice the vertex shader info, instead

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.

4b3bbe0ecd gl renderer: Create shader-global uniform ops on draw() 
This way we can render the first frame of tests/testoutsetshadowdrawing
in 153 ops instead of 183.

And the first frame of gtk4-demo in 260 instead of 300.

a8213d7f45 gl renderer: Avoid setting modelview to identical values 
The previous comment here was incorrect. We can save the op itself, we
just can't save us the entry in the modelview stack.

1ee4f6138b gl renderer: Reset opacity when rendering blend node children 
We render those on a texture, so we need to reset the opacity because
that will be applied when rendering the resulting texture.

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.

Fixes #3420

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.

08193ecf1c gl renderer: Generate queries only on desktop GL 
On desktop GL, GL 1.5 or GL_ARB_occlusion_query is required to get the
glGenQueries() etc. symbols.  This isn’t the case on GLES, where they
are provided by GL_EXT_occlusion_query_boolean, and more importantly
have never been made core.

This patch allows gtk4-demo to start when GDK_DEBUG=gl-gles is set, on
my Mali 400 MP running the Lima driver from Mesa.
