If we see custom fonts when serializeing text nodes, write data
url that contains the font file, the first time we see it.
This does not add blobs standard fonts, like Cantarell or Monospace.
Update all affected nodeparser tests.
This will let us store complete test fonts inside node files,
as data: urls. You can also use a file: url to refer to a local
file.
The syntax is as follows:
text {
font: "FONT DESCRIPTION" url("data:font/ttf;base64,FONT DATA");
}
with the url being optional.
Tests the fix in the previous commit 93715b963e.
Sadly, the flipped variant of this test fails with the cairo
renderer, so it is marked as -nocairo. All the other renderers
pass it.
Instead of setting FONTCONFIG_FILE to a custom font configuration,
pass the directory containing the fonts as TEST_FONTS and use
FcConfigAppFontAddDir to add them to the default font configuration.
Whether or not switches include shapes to indicate their ON/OFF
state is currently controlled by the stylesheet (in particular
the HighContrast style).
However there are use cases for both using the HighContrast style
without shapes, and for using shapes with the regular stylesheet,
so follow the newly added "show-status-shapes" setting instead.

This tests the fixes in aa82190da659b5 and dcaa2c4ccb182c74cb40.
The test uses a custom font named 'text-mixed-color' which contains
six glyphs that are just boxes. Glyphs 1, 2, 3 are just plain glyphs,
and glyphs 4, 5, 6 are color glyphs in red, green and blue.
The glyphs are mapped to the characters A, B, C, D, E, F.
The test is currently disabled for cairo, since it has some issues
with transformed color glyphs.
The commit adds a custom fontconfig configuration in
testsuite/gsk/fonts/fonts.conf and sets the FONTCONFIG_FILE
environment variable for the gsk compare tests to point at it.
To use a custom font in tests, just drop it into the
testsuite/gsk/fonts/ directory.
The font configuration includes the system configuration,
so existing tests should not be affected.
Fill a rectangle with fractional coordinates << 1.0 but scale it up so
that it ends up being nice integers.
Makes sure that nobody does any bad rounding here.
The Vulkan renderer can just be public API, because it doesn't expose
any Vulkan-specific APIs.
And it can just exist when compiled without Vulkan, because it can fail
to realize.
Also move get rid of the gsk/vulkan/gskvulkanrenderer.h header. It was
experimental and isn't necessary now that the renderer is included via
gsk.h.
Add a testsuite called gsk-compare-vulkan to run
the gsk renderer tests with the Vulkan renderer and
gsk-compare-ngl to run them with the NGL renderer.
To run the tests locally, you can do:
meson test -C_build --suite gsk-compare-vulkan
gdk_texture_save_to_png_bytes() cannot fail, so ensure that it doesn't.
Testsuite has been updated to check for this case.
Note that we do not load the PNG file that we generate here.
Loading is a lot more scary than saving after all.
If people want to load oversized PNG files, they should use a real PNG
loader.
If there are more than 7 color stops, we can split the gradient into
multiple gradients with color stops like so:
0, 1, 2, 3, 4, 5, transparent
transparent, 6, 7, 8, 9, 10, transparent
...
transparent, n-2, n-1, n
and use the new BLEND_ADD to draw them on top of each other.
Adapt the testcae that tests this to use colors that work with the fancy
algorithm we use now, so that BLEND_ADD and transitions to transparent
do not cause issues.
We want to introduce a new one next.
Technically, this breaks API, because gsk_vulkan_renderer_new() is going
away, but practically, we're gonna bring it back once we introduce that
renderer in a few commits.
The test ensures that offscreens render to the same pixel grid as the
actual image, and they are not offset by fractions of a pixel.
The Cairo renderer fails here because Cairo's clipping code rounds pixel
values wrong.
Testcase included
The code was writing invalid memory, so this might not have always
crashed, but I did my best to write the test so it causes a SEGV.
Also included is a fix for the testsuite where the expected result was
wrong.
The replayed node/images weren't saved.
I wanted to check that an optimization is done when replaying a test,
but without a saved node file, I couldn't.
It is not material to this test, and it causes some hard to
understand problem with fontconfigs use of mmap, leading to
a sporadic segfaults in pangos fontconfig thread.
This test fails on my system currently, since rawhide libpng appears
to have changed the encoding of pngs so that the texture nodes no
longer match the reference. This will be a problem as long as our
ci systems have an older libpng, so disable this test for now.
These 2 rectangles used to intersect fine:
0 0 50 50 / 50 0
0 0 50 50 / 0 50
But the computed result was:
0 0 50 50 / 50
which is not a valid rectangle, because the corners overlap.
Make sure such rectangles return NOT_REPRESENTABLE.
The above rectangle has been added to the testsuite.
