32588939ae Deprecate the adjust_baseline adjust_line_height and adjust_column_width options in favor of modify_font 
Unifies handling and allow using pt units for those adjustments.
Note that the behavior of percentage sizes for adjust baseline is
backwards incompatible. It now uses the baseline value as the base
rather than the cell height.

39b3d3de0f macOS: Fix the baseline for text not matching other CoreText based applications for some fonts 
Finally found an API to query CoreText for the adjusted baseline
position, so the baseline should now match up with other CoreText
based applications.

1f4fdb174a Fix rendering of the new infinite length ligatures on CoreText 
Apparently on CoreText, harfbuzz gives incorrect values for glyph
positions. So we use it only for selection and grouping of glyphs.
Actual positioning is done using CoreText. This means sophisticated
positioning using GPOS tables is probably broken, but that isn't really
useable in a character grid anyway.

Also remove the hack where glyph_centering was done for calt ligatures
as it seems to not be needed with modern FiraCode and CoreText
rendering. Fixes #3372

931e91f1a7 Read strikethrough info from font when using FreeType 
This reads the strikethrough position and thickness from the font so it
is rendered correctly.

This is only implemented for FreeType, not Core Text, because I didn't
find any way to get the info from Core Text, and I don't have a Mac to
test it on either. When using Core Text or when the font doesn't provide
the info, the same approximation as before is used.

4b65b4ac2b Fix potential undefined behaviour 
When `gray_color_space` is `NULL`, it is passed into `CGBitmapContextCreate()`. Since there are no guarantees in https://developer.apple.com/documentation/coregraphics/1455939-cgbitmapcontextcreate?language=objc to what happens in that case, depending on the implementation there may be undefined behaviour.

8dea5b3e3e Reduce data sent to GPU per draw by 30% 
Split up the Cell structure into a CPUCell and a GPUCell. Only the
GPUCell part needs to be sent to the GPU. Should make kitty use even
less system resources and make a performance difference on systems where
the GPU bandwidth is constrained.

Also allows adding more CPU only data in the future without affecting
GPU bandwidth. For example, hyperlinks or more combining characters.
