Some compositors will provide 'nicer' / 'human readable' output descriptions via the xdg-output protocol. Use these description strings, when available, instead of the model name provided by wl-output. On compositors such as GNOME where this is provided, the display names provided to applications by SDL will now match those in the desktop display settings panel. On compositors where this data isn't provided, the old behavior of using the model string provided by wl-output will remain unchanged.
Additionally, per the protocol spec, output data provided by xdg-output should supersede wl-output data, so this is the recommended behavior in general.
If the width is sufficiently ludicrous, then the calculated pitch or
the image size could conceivably be a signed integer overflow, which
is undefined behaviour. Calculate in the unsigned size_t domain, with
overflow checks.

When SDL is built with Wayland support on Linux, and Wayland libraries
are linked as dependencies instead of being loaded with dlopen(), its
dependencies will include libraries whose names contain a dash, like
`-lwayland-client` and `-ldecor-0`. Don't replace such libraries with
`-lwayland` and `-ldecor`: those don't exist and linking them will fail.

As mentionned in libsdl-org/SDL_net#48 and libsdl-org/SDL_ttf#213:
- Options needs to use `SHELL:` to avoid aggressive option de-duplication
- Framework path needs to be quoted to support paths with spaces.
Fixes bug with viewport not updating when moving window between monitors with different scale
factors on Windows (this should also fix the same issue on other OS'es, though untested)
Adds hint "SDL_WINDOWS_DPI_SCALING" which can be set to "1" to
change the SDL coordinate system units to be DPI-scaled points, rather
than pixels everywhere.
This means windows will be appropriately sized, even when created on
high-DPI displays with scaling.
e.g. requesting a 640x480 window from SDL, on a display with 125%
scaling in Windows display settings, will create a window with an
800x600 client area (in pixels).
Setting this to "1" implicitly requests process DPI awareness
(setting SDL_WINDOWS_DPI_AWARENESS is unnecessary),
and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows.
