This update brings some significant changes to the Cascadia family:
* Arabic and Hebrew support
* Italics (the new ones, not the cursive ones)
* Tweaked letterforms and fixed interpolation values for the upright
faces.
Since we now have four font files, this commit also relocates them to a
much more reasonable place (res/fonts/) and tidies up the build and
exclude rules to make them more extensible in the future.
This update fixes some issues in Cascadia Code's February update:
microsoft/cascadia-code#406 - updated anchor type to lock with the other equals-related ligatures
microsoft/cascadia-code#408 - corrected component used for glyph to align with Unicode
microsoft/cascadia-code#412 - updated locl features removing iacute_j ligature and Catalan substitution
microsoft/cascadia-code#414 - increased overlaps of middle glyph for arrow ligatures
microsoft/cascadia-code#415 - reduces width of macronbelow
microsoft/cascadia-code#416 - rolls back name ID 4 modification as JetBrains cannot process it correctly
microsoft/cascadia-code#428 - rolls back variation of the underline to prevent MVAR table generation
Full changelist:
* Repositioned tilde in related ligatures. Previously it was higher than the standard one.
* Added missing vietnamese anchors on acute and grave (futureproofing).
* Corrected / made consistent greater & less positioning in </> and <$> related ligatures.
* Otherwise reviewed hinting
It was brought to our attention that shipping a font with ligatures as our default
font could be an accessibility issue for the visually-impaired. Unfortunately, we
don't have a renderer setting to disable ligatures (#759). Fortunately however, we
DO already have a version of Cascadia that doesn't have ligatures.
If we ship that and set it as our default font, we'll at least let people _opt_ to
have ligatures enabled by switching from `Cascadia Mono` to `Cascadia Code`.
