When set, the cursor-invert-fg-bg option uses the inverted foreground
and background colors of the cursor's current cell to color the cursor,
rather than using a fixed color. This option has higher precedence than
the cursor-color and cursor-text options, but has lower precedence than
an OSC 12 command to change the cursor color.
Some CoreFoundation objects, such as those produced by CoreText, have
expensive callbacks that run when they are released. By offloading the
CFRelease calls to another thread, we can avoid important threads being
blocked by unexpectedly expensive callbacks.
This commit also changes the way that the coretext shaper's run iterator
builds its string. Rather than using a CFMutableString, an ArrayList of
unichars is built which is passed to CFStringCreateWithCharactersNoCopy,
which is a lot more efficient since it avoids all the CoreFoundation
overhead.
Fixes#1784
This was just a misunderstanding of the "spec." When both a y offset
into the image is specified and a height, the image should be stretched.
I mistakingly thought that the image should be offset (even with this
misunderstanding there was a data corruption bug).
This resolves the issue and output matches Kitty.
When hot reloading config with a new font, shaper cache data needs to be
invalidated and the font grid needs to be rebuilt. This change just
makes that happen on all config reloads since it's a rare action so it's
not a performance concern.
This will allow for unlimited glyphs per row, eliminating the issue run in to with multi-substitution glyphs and combining characters which can result in more glyphs in a row than there are columns.
Previous version prevented multiple glyphs from belonging to the same coordinate, which broke quite a few things. This implementation fixes that (and may be more efficient too). Needs clean-up.
I introduced screen dirty flags fairly late, and never reset them. As a
result, dirty tracking basically gets disabled as soon as selection
changes in any form. This happens frequently because _unsetting_
selection also resets selection which happens for various events.
