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.

28c4adac24 Fix gtk4-demo’s gears demo on OpenGL ES 
Here is a command to reproduce this testcase:
GDK_DEBUG=gl-gles gtk4-demo --run gears

Without this patch, Mesa throws this compile error:
0:130(13): error: no matching function for call to `mod(error, float)'; candidates are:

This is caused by `u_rotation - 90` being of type error since
`u_rotation` is a float and it’s illegal to subtract it with an integer.

dee863dbb2 rendernode: Bail if matrix is invalid

9cec9e4ce2 gsk: Export the glyph serialization privately 
We want to use the same serialization in the inspector,

26119af7a6 gsk: Improve glyph serialization 
The special case for ASCII glyphs is unfortunately not
working very well, because of an oversight in pango:
When I added subpixel positioning, I made pango_shape()
default to not rounding, and make PangoLayout call
pango_shape_with_flags() and pass the rounding information
down. The upshot is that we need to use the _with_flags
variant here and tell it to round position, so it matches
what the text node contains.

aa95ae774f gsk: Fix serialization of glyphs 
We were forgetting to put a space between two numbers
in some cases, confusing the parser.

Test included.

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

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.
