Compare clipped repeat nodes. Must skip cairo here
since it blurred the child by scaling after rendering.
Also skip the gl renderer, since it hasn't been fixed
for this yet. ngl passes this test.
When we are rendering a texture node to an offscreen,
and we have a clip, we must force the offscreen rendering.
Otherwise, the code will notice: Hey, it already is a texture
node, so no need to render it to a texture again. But when
clipping is involved, that is exactly what we want to do.
Testcase included.
Fixes: #3651
If the inner clip intersects with the corners of the outer clip, we
potentially need a texture. We should add more fine-grained checks for
this in the future though.
Test case included.
We don't need to just look at the scale of the new modelview matrix, but
at the one we get when multiplying the new one with the current one.
Test case attached.
Use cairo-script-interpreter to parse the scripts that generate cairo
nodes.
This requires libcairoscriptinterpreter.so to work properly, but if
it isn't found we disable this (unimportant for normal functioning)
code and just emits a parser warning.
The testsuite requires it however or it will fail.
A new test is included that tests all of this.
Test that rendering empty nodes succees. For a lot of nodes the
resulting rendering isn't clearly defined, in those cases we overdraw
those regions (sometimes the whole image) with black.
Instead of encoding the raw data, encode the full image to a PNG.
And instead of stuffing that encoding into a string, use a full
data: url.
And then remove the width and height properties, because they're now
implicitly included in the data.
And then change the parser to match.
And because the parser now parses regular urls on top of data: urls, we
can now load any random file.
