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.
Instead of using the bounds of the clip region, emit individual
renderpasses for each rectangle of the clip region.
The benefit of this depends on how many pixels the clip region covers,
but for widget factory it reduces the required rendering by a huge
amount.
This is now the best clipping renderer - Cairo doesn't clip at all and
GL clips based on the extents.
Previously, we would set a scissor rect when doing a partial redraw, but
we would not clip the nodes based on that rectangle.
Do that now.
This massively reduces the amount of ops we emit for small redraws.
