3f0a830f3c Properly annotate the render node constructors 
Now that the GskRenderNode subclasses are recognised as proper
sub-types, we can annotate the constructors with their type. The C API
remains the same.

e0323fcdc2 Add get_type() functions for GskRenderNode subclasses 
The introspection scanner tries to match a type name with a get_type()
function, in order to correctly identify a type as a class.

If the function is not available, we have two choices:

 - add some special case inside the introspection scanner, similar to
   how GParamSpec subclasses are handled in GObject
 - add a simple get_type() function

The latter is the simplest approach, and we don't need to change that
much, since we still register all render nodes at once.

cd5cded430 Do not install GSK headers for missing backends

d701a89281 Turn GskRenderNode into a derivable type 
Language bindings—especially ones based on introspection—cannot deal
with custom type hiearchies. Luckily for us, GType has a derivable type
with low overhead: GTypeInstance.

By turning GskRenderNode into a GTypeInstance, and creating derived
types for each class of node, we can provide an introspectable API to
our non-C API consumers, with no functional change to the C API itself.

777435c470 meson: Reduce useless relinking on reconfigure 
When we reconfigure, `configure_file()` is called again, and
`*.gresource.xml` files are regenerated, which causes many (all?)
binaries to be relinked. Now we only write those out if the contents
actually changed (or if the output didn't already exist).

This is exactly what Meson already does with `configure_file()` when
`command:` is not used.

While we're at it, also do the same for `gen-c-array.py` and
`gentypefuncs.py` for completeness. Now even if the input to those
changes, re-building of those custom targets may not result in
relinking if the outputted C files have the same contents.

e356d59a92 build: Add -Wnull-dereference 
Sprinkle various g_assert() around the code where gcc cannot figure out
on its own that a variable is not NULL and too much refactoring would be
needed to make it do that.

Also fix usage of g_assert_nonnull(x) to use g_assert(x) because the
first is not marked as G_GNUC_NORETURN because of course GTester
supports not aborting on aborts.

  I * B = B
so just return B.

0969d06925 Fix detection of OpenGL 3.3 core GL_ARB_timer_query. 
Some systems (notably macOS) will not allow enumeration of an extension that has been promoted to core OpenGL for context in use. This change assumes that GL_ARB_timer_query is available on OpenGL 3.3+.

I could not find definitive information on whether GL_ARB_debug_output or GL_KHR_debug have been added to core. Other extensions in use were addressed by https://gitlab.gnome.org/GNOME/gtk/merge_requests/1422 .

f0993fc881 rendernode: Avoid rounding errors 
Compute the pattern matrix directly instead of transforming the cairo_t.

This ensures that when node_size / texture_size is some obscure floating
point value, we don't get rounding issues from scaling by it once we
draw the texture_size rectangle.

I have no actual failure where this comes in handy, but I had written
the code anyway, so decided to keep it.

This is because unlike integer math, floating point cannot do the "as

2890cd849f profiler: Add _end_mark() version of _add_mark() 
These don't take a duration, instead they call g_get_monotonic_time() to
and subtract the start time for it.

Almost all our calls are like this, and this makes the callsites clearer
and avoids inlining the clock call into the call site.

01d5ad2056 profiler: Make profiler-is-running a macro 
When we use if (GDK_PROFILER_IS_RUNNING) this means we get an
inlined if (FALSE) when the compiler support is not compiled in, which
gets rid of all the related code completely.

We also expand to  G_UNLIKELY(gdk_profiler_is_running ()) in the supported
case which might cause somewhat better code generation.

cc643df88b Convert all profiler times from nsec to usec 
usec is the scale of the monotonic timer which is where we get almost
all the times from. The only actual source of nsec is the opengl
GPU time (but who knows what the actual resulution of that is).

Changing this to usec allows us to get rid of " * 1000" in a *lot* of
places all over the codebase, which are ugly and confusing.

7b0b3d9547 GskGLRenderer: Share programs between different renderers in same display 
This is similar to how we share texture atlases. Some added complexity
in that the program state also needed to be shared, so it had to move to
the shared Programs object.

With this change realization of additional GskRenderers when opening

1f0438e7fe gsk: Fix angle normalization 
I was getting assertions that normalize_angle() failed the
result < 260 check. Doing some research on this it turns out
to be a precision issue. If the incomming angle is very slightly
below zero, then adding 360 to it may end up with exactly 360.

I simplified the code a bit to avoid division and rounding, because in
practice most angles will be "just outside" the 0-360 degree anyway.
And i also added a workaround for the "result is 360" case by just
setting it to 0.

8fdb710c0f gl: Don't require too large texture for offsreen ops 
When rendering ops to an offscreen texture we take max-texture-size
in consideration and modify the scale we use such that the required
texture does not exceed the limit.

This means some rendering will be blocky/fuzzy, but that is better
than it being clipped.
