This patch allows to insert "%uid" in `IPC_CLIENT_CONNECTION`
declaration and in SystemServer's ini files. This pattern is replaced
then replaced by the UID of the owner of the service. It opens a path
for seamlessly managed, per-user portal.
The `/tmp/user` directory is owned by root, this solution prevents
malicious users to interfere with other users' portals.
This commit also moves `launch`'s portal in the user directory.
The median filter replaces a pixel with the median of all pixels
(usually grey value is used) in a square neighborhood. This is a
standard image processing filter used for denoising, as despite its
simplicity it can e.g. retain edges quite well.
The first implementation is quite inefficient mostly to environmental
constraints. Due to how images are passed to the processing function,
two unnecessary copies happen. And because there's no fast sorting
algorithm for small arrays (insertion sort) yet, quick sort needs to be
used which is quite slow on this scale.
This makes modifications in FontEditor more visible, both so you know
what you've changed, and for taking a handy "here's what's changed"
screenshot for a font PR. :^)
The background color for new glyphs is green, modified glyphs is blue,
and deleted glyphs is red. The changes persist until you load a new
font file, so you can continue saving your work as you go and still be
able to take a convenient screenshot at the end.
I didn't feel like this one use was enough to add 3 new color roles to
themes, so to make this look decent on dark themes, it detects if the
theme is marked as dark, and uses darker colors for the highlights
which look nice with a light text color.
Neither of the tests here actually passes properly right now. It's a
little more aspirational...
In the first one, the circle draws in the wrong place due apparently to
existing bugs in `CanvasRenderingContext2D::ellipse()`.
In the second, I just haven't yet implemented creating a Path2D from an
SVG path string, because that's going to take a fair bit of untangling
first.
If absolutely positioned divs do not have a fixed position, then their
position must be calculated based off of the position of their parent
and their siblings.
Factor out the code that computes the vertical position of a Box with
respect to its siblings so that it can be used when computing the
absolutely positioned divs as well.
The tooltip window didn't resize when setting a shorter text, or moving
to a widget with shorter text, so it had extra space on the sides.
Fix by allowing the window to resize without obeying the minimum size
of the (previous) tooltip.
