This method is used to generate headers for embedding files into the binary
(think about the new `#embed` feature in C23 and C++26).
While the stringification step itself was plenty fast, it then proceeded
to wrap everything using the `textwrap` module. `textwrap` is *very*
slow, as it's apparently optimized for human text.
This patch reimplements the wrapping logic using a simple regex,
resulting in a tremendous speed improvement (~6x), and switches to `map`
for the stringification itself (thanks Rémi!)
It also removes a (practically) unused argument, `initial_indent`.
The generated files are pretty much the same, with a tiny difference in
line length (for some reason the old logic overshot the requested line
length)
Introduces support for FSR2 as a new upscaler option available from the project settings. Also introduces an specific render list for surfaces that require motion and the ability to derive motion vectors from depth buffer and camera motion.
