When we don't have an embedded font file via a url, then we want
to parse fonts "as normal", i.e. allow fallback for aliases like
"Monospace 10". This was broken when the url support was added.
Make it work again.
Update affected tests. In particular, the output of the text-fail
test goes back to be the same it was before the url changes.
GL needs version 4.2 before it supports explicit bindings. We use GLES
usually, and Mesa supports GL 4.6, so we didn't hit this case before.
However, MacOS does use GL and Mac OS is stuck on GL 4.1.
Fixes#6363
The intent of this change to get wider testing and verify that the
new renderers are production-ready. If significant problems show
up, we will revert this change for 4.14.
The new preference order is ngl > gl > vulkan > cairo.
The gl renderer is still there because we need it to support gles2
systems, and vulkan still has some rough edges in application support
(no gl area support, webkit only works with gl).
If you need to override the default renderer choice, you can
still use the GSK_RENDERER environment variable.
When a border side has a width of 0 but we're having rounded corners, we
draw content in the edges of that side, and naturally pick its color.
That is wrong though, when the width is zero, we're supposed to keep
using the color of the other side in that corner.
So do that.
Fixes the border-corner-zero-width-rendering.ui reftest.
Count how many dead pixels we have, and free the atlas if more than
half of its pixels are dead.
As part of this, change when glyphs are freed. We now keep them
in the hash table until their atlas is freed and we only do dead
pixel accounting when should_collect is called. This keeps the
glyphs available for use from the cache as long as are in the atlas.
If a stale glyph is sused, we 'revive' it by removing its pixels
from the dead.
This matches more closely what the gl renderer does.
If we gc a cached texture for which the GdkTexture is still alive,
the cached texture object will remain accessible via the render
data, so need to make sure not to leave a dangling pointer behind
here.
This is straightforward. If a texture hasn't been used for 4 seconds,
we consider it stale, and drop it the next time gc comes around.
The choice of 4 seconds is arbitrary.
Fixes: #6346
Add GSK_GPU_SKIP=glyph-align to turn off the glyph aligning.
FIXME: Should this be handled by the renderer at all or should we rely
on higher rendering layers to align glyphs properly?
This is kind of a tricky question just like with texture-scale nodes and
NEAREST filtering, because rendernodes can be embedded in other nodes
that disturb the pixel grid.
Previously, we only checked if the cache had exhausted the maximum
number of slices.
But we also need to check that the height of the slices doesn't exceed
the height of the texture.
After the node-editor crashed on me once too often, I decided to take a
good hard look at the parsing code and add a bunch of weird corner
cases into the testsuite.
That meant redoing the parser so that the error paths cause neither
crashes nor duplicated or wrong error messages.
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.
A PangoFont keeps a weak reference to its fontmap. In addition,
keep a strong reference in GskTextNode, so we can be sure that
custom font maps won't go away before the node is finalized.
This clip is different from "none" in that the bounds rect cannot be
ignored and that potential drawing outside the clip must be avoided.
In particular it means that clip nodes cannot be discarded if they
encompass the full clip region.
Fixes#6322
Make sure fallbacks and fill/stroke masks use image surfaces with the
same pixel grid as the target if possible.
Fixes blurriness with some path renderings.
We need to respect the offset when converting to the pixel grid, so pass
the current offset into the function.
Also move the rounded out of gsk_gpu_get_node_as_image() and into the 2
callers, because the offset is not passed into the function and I see no
reason to change that.
