4a0d3d7acc docs: Reduce redundancy
Remove a boatload of "or %NULL" from nullable parameters
and return values. gi-docgen generates suitable text from
the annotation that we don't need to duplicate.

This adds a few missing nullable annotations too.

7fe0610b68 introspection: Stop using allow-none
allow-none has been deprecated for a long time
already. Instead use optional and nullable everywhere.

66b4f0cac4 ngl: Reuse texture coordinates
When uploading glyphs, reuse the position that
we get from gsk_ngl_texture_library_pack, instead
of recomputing it.

81e0206465 ngl: Be consistent about padding
Make gsk_ngl_texture_library_pack always return
the position including the padding. And compute
texture coordinates accurately in all cases (we
were fudging the padding for standalone textures.

930ff499ee Confine -mf16c to a single source file
We can't use this flag for any code that may get run
outside the __builtin_cpu_supports() check, and meson
doesn't allow per-file cflags. So we have to split this
code off into its own static library.

c66b030427 ngl: Fix a rare assertion violation
When we clean up the uniform allocations after a frame,
it can happen that our space requirements actually increase,
due to padding that depends on the order of allocations.

Instead of asserting that it doesn't happen, just make
it work by growing our allocation.

Fixes: #3853

d5ced21264 gsk/ngl/fp16.c: Implement runtime F16C detection on MSVC
We need to use __cpuid() to check for the presence of F16C instructions on
Visual Studio builds, and call the half_to_float4() or float_to_half4()
implementation accordingly, as the __builtin_cpu...() functions are strictly
for GCC or CLang only.

Also, since __m128i_u is not a standard intrisics type across the board, just
use __m128i on Visual Studio as it is safe to do so there for use for
_mm_loadl_epi64().

Like running on Darwin, we cannot use the alias __attribute__ as __attribute__
is also for GCC and CLang only.

f8f2f2944f roundedrect: Speed up contains_rect and friends
gsk_rounded_rect_contains_rect was calling

corner/point checks. But there is no need to do
more than 4 such checks to answer the question.

0caa28c1de ngl: Optimize underlines in text
Opportunistically use the coloring program for

This avoids program changes in the middle of
text.

the program changes per frame from > 1000 to around 100.

885a6b8ebc gsk: Add runtime checks for F16C
Use an IFUNC resolver to determine whether we can use
intrinsics for FP16 conversion. This requires the functions
to be no longer inline.

Sadly, it turns out that __builtin_cpu_supports ("f16c")
doesn't compile on the systems where we want it to prevent
us from getting a SIGILL at runtime.

ae7f52d301 ngl: Reduce vertex storage
We only have one shader that uses the color2 attribute,
and it doesn't use the uv attribute, so save vertex
memory by putting those in the same space.

8b1fcb58e8 ngl: Use fp16 for colors
This reduces the size of our Vertex struct from

the colors in fp16 format in the rendernodes, and
avoid conversion here. But this is still good.

efb5e793a4 nodeparser: Change the serialization

8d603dfe99 ngl: Avoid huge intermediate textures
Instead of rendering the unclipped child to a texture
(and risking blowing the texture size limit, and bad
downscaling), just render the clipped region, and live
with the fact that we can't cache the rendered texture.

This avoid bad artifacts when scrolling long textviews
in rounded clips.

f9457af128 ngl: Fix offscreen rendering with transforms
There was confusion here about the handling of the
modelview transform. The modelview transform we are
getting is already set up for rendering the node
we are given, so keep it - except for possible adding
an extra scale on top when the texture would otherwise
be too big.

3add99a9a8 ngl: Speed up glyph loop
