To reduce compile-times and avoid some overhead to binary size, this will modify some of our
generic functions to use non-generic inner functions where possible. The inner functions are
marked carefully with `#[inline(never)]` to prevent being inlined by LLVM at their callsites
While looking for generic functions to optimize, I have also taken the opportunity to annotate
public non-generic getters and setters with `#[inline]` to ensure that LLVM will inline them
across crate boundaries. By default, only generic functions are automatically inlined, and
only when enabling fat LTO are constant functions reliably inlined across crate boundaries.
The string cache used by ustr pre-allocates 12 MB, even if we're
only using it for a few font family names. We can therefore
manage our own set of leaked strings to reduce memory usage by 12 MB.
Better support for multi-threaded applications,
especially cosmic-comp rendering in parallel on
multiple threads, each potentially accessing
global configurations such as the active theme,
icon_theme and more...
