This allows one to build Raspberry Pi versions on an ancient version of
Raspbian and get both the KMSDRM and RPI video targets built into SDL, giving
maximum binary compatibility from linking against an older glibc, etc, but
also making one library that can access video on all RPi models and OS
releases.

Basicly there is problem and somewhat a solution: https://discourse.libsdl.org/t/setwindowmaximumsize-bug/28267
If you SDL_SetWindowMaximumSize() after SDL_SetWindowMinimumSize() with one of axes have the same value, function will have no effect.
This: (line 2144@SDL_video.c)
if (max_w <= window->min_w || max_h <= window->min_h) {
SDL_SetError("SDL_SetWindowMaximumSize(): Tried to set maximum size smaller than minimum size");
return;
}
May be changed to this:
if (max_w < window->min_w || max_h < window->min_h) {
SDL_SetError("SDL_SetWindowMaximumSize(): Tried to set maximum size smaller than minimum size");
return;
}
When converting audio from signed to unsigned values of vice-versa
the silence value chosen by SDL was the value of the device, not
of the stream that the data was being put into. After conversion
this would lead to a very high or low value, making the speaker
jump to a extreme positon, leading to an audible noise whenever
creating, destroying or playing scilence on a device that reqired
such conversion.
UnmapNotify event does not mean that window has been iconified. It
just reports that window changed state from mapped to unmapped.
XReparentWindow can unmap and remap window if it was mapped. This
causes unnecessary events - HIDDEN, MINIMIZED, RESTORED and SHOW.
These events are problematic with Metacity 3.36+ which started to
remove window decorations from fullscreen windows.
- SDL makes decorated window fullscreen
- Metacity removes decorations
- SDL gets UnmapNotify and exits from fullscreen
- Metacity re-adds decorations
As SDL will also get MapNotify event it will try to restore
window state causing above steps to repeat.

Add a minimal my_gradd.h containing structures and constants only used
by SDL_os2vman.c -- based on public knowledge from around the internet
including pages from http://www.osfree.org and http://www.edm2.com .
Original code assigned MCIMixSetup.ulSamplesPerSec value to it, but it
is just the freq... We now change spec->samples only either if it is 0
or we changed the frequency, by picking a default of ~46 ms at desired
frequency (code taken from SDL_audio.c:prepare_audiospec()).
With this, the crashes I have been experiencing are gone.
