Fixes#1409
Fixes macOS 14.4,14.5 kernel panics
As noted in the comment in this diff, I've decided to default this to
true because it fixes a couple _really bad_ issues for macOS users. For
macOS users on 14.4 and 14.5 (latest released as of this commit), this
resolves or at least heavily mitigates a possible kernel panic.
This also fixes#1409 where external displays over certain connections
such as DisplayLink would be unusably slow to render.
Partial fix for link highlight dirty tracking. Some issues remain with
soft-wrapped links (see TODO in code), as well as pressing cmd while
hovering without moving the mouse at all doesn't highlight until you do
move the mouse for some reason.
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.
Allows for high dpi displays to get odd numbered pixel sizes, for
example, 13.5pt @ 2px/pt for 27px font. This implementation performs
all the sizing calculations with f32, rounding to the nearest pixel
size when it comes to rendering. In the future this can be enhanced
by adding fractional scaling to support fractional pixel sizes.
Now that we're padding the cells with blanks if we have shaped ligatures
we don't actually know the exact count based on the CoreText APIs, so we
should just dynamically add.
bash reads HISTFILE at startup to locate its history file, but this is
apparently too early for it to be able to expand home-relative paths. We
now manually expand the full path and add that to the environment.
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.
