Removes some verbiage and arranges things consistent with other
settings dialogs.
Ideally we shouldn't litter UIs with shortcuts, tips, tricks,
self-evident or redundant descriptions, etc, so this can be
refined again in the future once there's an official way to expose/
customize keyboard shortcuts.
This was disabled originally because of performance paranoia, but it
resulted in flickering sometimes, so let's err on the side of nicer
looking terminals. :^)
Using the fact that there are 2^52-2 NaN representations we can
"NaN-box" all the Values possible. This means that Value no longer has
an explicit "Type" but that information is now stored in the bits of a
double. This is done by "tagging" the top two bytes of the double.
For a full explanation see the large comment with asserts at the top of
Value.
We can also use the exact representation of the tags to make checking
properties like nullish, or is_cell quicker. But the largest gains are
in the fact that the size of a Value is now halved.
The SunSpider and other benchmarks have been ran to confirm that there
are no regressions in performance compared to the previous
implementation. The tests never performed worse and in some cases
performed better. But the biggest differences can be seen in memory
usage when large arrays are allocated. A simple test which allocates a
1000 arrays of size 100000 has roughly half the memory usage.
There is also space in the representations for future expansions such as
tuples and records.
To ensure that Values on the stack and registers are not lost during
garbage collection we also have to add a check to the Heap to check for
any of the cell tags and extracting the canonical form of the pointer
if it matches.
When the given needle is not found, replace displays a widget that says
the needle is not found, but replace all does not.
This change adds that widget to replace all.
This fixes an issue where the window resize overlay would display
inaccurate "columns x rows" after a font change. This happened because
we kept using size increments derived from the original font.
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.
Effects tab provides the UI for setting SystemEffects.
DisplaySettings is getting a bit crowded and might need a re-org
at some point, but this seems like a good home for effects while
the settings mature.
This patch replaces the concept of fixed resizees with opportunistic
ones which use the new SpecialDimension::OpportunisticGrow UISize.
This lets us simplify splitter resize code and take advantage of
the layout system's automatic calculations for minimum size and
expansion. Functionally the same as before, but fixes Splitter's
unintended ability to grow window size.
Adds fallible functions for opening and saving fonts and cutting
and copying selections. FontEditor now falls back on a guaranteed
default BitmapFont on startup. Fixes crashing on start when the
default system font is set to TrueType.
When you press the escape key in the Browse dialog, the key down event
closes the dialog while the key up event then closes the Run window.
Prevent this by only listening to key down events.
