* Variable font support
Here's a pretty naïve solution for variable fonts.
The iterator doesn't use the match keys' weight, but instead tries to
get the requested ideal weight, if the font is variable, otherwise it is
ignored and the actual (non-variable) weight is used. This is because I
didn't implement finding variable weight support for match keys; doing
so would be impossible without parsing TTF files when matching and I
didn't want to add that potentially expensive infrastructure if not
entirely necessary.
This is a breaking change, and I'm open for ideas on how to fix that
if it's an issue.
* cargo fmt
* Add variable font example to rich-text example
Font family know gets used when querying the font.
Not sure if this solution is good, if the old code is even needed.
This works for me, which makes it good enough for me.
Due to https://github.com/pop-os/cosmic-text/pull/141 the LayoutRunIter incorrect checks to see if the baseline is past the visible bounds of the buffer, instead of using the maximum ascent and maximum descent from the baseline.
We want byte indices, not code point indices. Fixes a panic when
selecting the mixed-language text at the bottom of the rich-text example
when the shaping mode is set to "Basic".
Before this change, scrolling down when there were multiple layout lines, that rendered beyond the screen, would not work properly. This is because the current logic only acts if there are two or more buffer lines, calculating the proper layout height for each line.
This adds an edge case check for single lines, ensuring the case is handled.
