* Always use fractional font sizes

NOTE: The grid is still integer sized, so it's rendered wrong

* Remove fudge factor

* Properly set a fractional grid size

* Disable baseline snapping, and enable rounding to integers for scroll offsets again

The baseline snapping needs to be disabled so that the lines are
properly placed, and not snapped to pixels. While using integer based
scroll offsets greatly reduces the pressure on the Skia font cache.

* Plot the skia cache sizes

* Improve the Skia font cache usage

A bigger default size with cleanup when idling

* Fix fractional border positions

* Update the documentation

* Enable baseline snap

* Ceil the font height to the nearest pixel

This improves the quality and the performance of the font rendering.

* Configurable text contrast and gamma

* Explicitly specify the colorspace to use

* Change default hinting to slight

Full hinting is a bit too aggressive, especially with fractional font sizes

* Update the documentation

* Cargo fmt

* Disable skia related stuff and add wgpu

* Draw an actual background color

* Use palette crate instead of Skia color

* Remove Skia and comment out some code to make it compile

* Somewhat working actual rendering

The layers don't render properly, the transparency doesn't really work,
and all cursor effects are disabled.

* Switch to Github version of Vide

* Hardcode the font

* Draw floating windows

* Draw border lines

* Proper clipping

* Hardcoded font y_adjustment

* More correct background colors

The format appears to be linear, but not quite. Maybe some precision
loss or something.

* Fix the profiling build, add some zones

* Ensure that the assets/embedded exists

* Add rust-toolchain.toml

* Update dependencies to latest version of Vide

Does not compile at the moment

* Switch to glamour instead of euclid

* Fixes to make the latest vide version work

* Fix the tests

* Update to Github version of Vide

* Delete D3D and Opengl implementations

* Delete GPU profiling related code

* Delete platform specific vsync implementations

* Change format of comments for easier diffs and merges

* Move hardcoded font size calculation back to caching shaper

* Cleanup the code from warnings

* Fix the tests

* Fix Windows and macOS builds

* Disable TSC check in the CI

* Downgrade pathfinder_simd to 0.5.2

* Delete rust-toolchain.toml, upgrade parley again

* More clippy fixes

* Delete unused embedded assets

* Update to Winit 0.30.3

Also Glutin 0.32, Glutin-winit 0.5.0 and raw-window-handle 0.6.0.

* Working Linux build

* Convert the main update loop to use Winit ApplicationHandler

* Conver the error window to Winit ApplicationHandler

* Fix macOS build

* Fix Windows build

* Update dependencies

* Precompute the lines

* Store font info

* Upgrade tracy profiler to be compatible with the latest one used by vide

* Remove redundant profiling frame event

* Reduce the amount of profiling events

* Make it possible to disable vsync

* Optimize some external dependencies in debug mode

Otherwise, the debug mode will be very slow, if the external dependency
needs to be debugged, then the optimization can be manually disabled.

* Draw the built-in profiler

* Draw cursor

* Update Vide

* Fix api breaking changes

* Clippy fixes
