gsk: Maintain clip info for glyph nodes
We can determine once whether we are contained, instead of doing
it again for every glyph.
The performance impact of this is hard to measure.

gsk: Don't add images needlessly
Most likely, the image for all glyphs will be the same atlas,
so check first before calling the add_image function, which
will loop over all images.
This matches what the pattern code does for glyph nodes.
The performance impact of this is hard to measure.

gsk: Split the glyph cache
Do the glyph cache lookup in two steps: First find a cache for
the given font+scale, then look up the glyph+flags. Since
font+scale change much less frequently (in particular, they are
the same for all glyphs in a text node), it makes sense to keep
the result of the last lookup around and check if it still fits.
Here are changes in running widget-factory with no-vsync:
before after
gsk_gpu_device_lookup_glyph_image 1.43% 1.02%
g_hash_table_lookup 0.76% 0.43%
gsk_gpu_cached_glyph_equal 0.28% 0.21%

gsk: Keep scaled fonts around
Create the scaled font on demand, only when we need to render a glyph,
and keep it around while processing the remaining glyphs in the text
node, rather than recreating it over and over.

gsk: Stop passing scale to glyph upload op
It is always 1.0 now, so there is no point. Instead of the scale,
print the font when doing verbose logging.

gsk: Use a scaled font for glyph rendering
This changes the approach we take to rendering glyphs in the
presence of a scale transform: Instead of scaling the extents
and rendering to an image surface with device scale, simply
create a scaled font and use it for extents and rendering.
This avoids clipping problems with scaling of extents in
the presence of hinting.

gsk: Add a way to get a scaled font
Add a function to change the size of a font while keeping everything
else the same. We use pango api for this if available.

application: Prevent a warning
When we've handled a inhibit idle request via Wayland, there is
no need to call into the D-Bus inhibit api unless there's other
inhibit flags to handle.
