This is for 3 reasons:
1. Separation of concerns
The device is meant to manage the Vulkan/GL device and check stuff
like image sizes.
Caching is not part of that.
2. Refcounting
Images etc want to reference the device, but the cache wants to
reference images. If the cache is the device, that's a refcycle.
3. Flexibility
It's now easier to implement >1 cache, say one per depth or one per
color state.
Keeping the GdkRGBA requires doing later conversions, which isn't
necessary if we just keep the already converted float[4].
It also prepares for future color states, where the color will need to
be converted using the colorstate.
Fill and stroke nodes were not reporting proper offscreen-for-opacity
and preferred depth.
This was unlikely to have been noticed as their child is usually a solid
color.
Despite my best effort, it seems impossible to make ci and local
builds agree on what font subsetter and fonts to use, so make this
opt-in for now: If you want to produce a node file with embedded
fonts, set GSK_SUBSET_FONTS=1.
The rendernode parser creates its own fontmap for the fonts that
we deserialize from blobs. But we were using the system fontconfig
configuration for it, leading to system fonts still being found.
This is bad, and causes test failures in ci. Try with an empty
fontconfig configuration instead.
Since GskTransform is immutable, a lot of the documented "methods" are
more like "functions", in the sense that they don't keep the instance
alive but rather consume it.
This is annotated with `(transfer full)`, but since these functions are
listed as methods, their first argument is not shown.
Instead, let's add a line to the docs of each consuming function that
clarifies this behavior.
Even if we disable font fallback, after adding Cantarell Regular
to the custom fontmap, fontconfig will helpfully synthesize
Cantarell Bold for us. So, just don't check for the font at all.
If there is a url, add it to the fontmap and leave it up to the
serializing code to ensure that we don't end up with duplicate
fonts.
The hb face is is a wrapper around the font file, which is what
we need to track here, since we want to subset and serialize each
used font file exactly once.
When serializing nodes, collect the glyphs that are used from
each font, subset the font to that set of glyphs, and embed it
into the node file. We are careful to preserve the glyph IDs,
so our text nodes transparently work with the subsettted fonts.
This way, we can simply duplicate the keys as separate pointers to store
the corresponding Vulkan handles so that we can safely hash them, as
Vulkan handles may or may not be pointers depending on the target
platform.
This will fix builds on 32-bit Windows at least.
This function does not use the standard __cdecl calling convention on
Windows, meaning using g_clear_pointer() on it directly will cause
crashes on 32-bit Windows. Just call it directly if the GLsync it uses
exists.
Switch symbolc icon drawing from color-matrix to mask nodes
make the performance of the iconscroll demo crater (from 60fps
to 10fps).
Apply the same optimization we already have for color-matrix
nodes when drawing mask nodes. This gets us back to 60fps.
Fixes: #6700
On Windows, gsize is a long long unsigned. The compiler complains about
that.
Use G_GSIZE_FORMAT which translates to %llu on Windows, %lu on most
platforms, and sometimes just %u on rare cases.
