Rounding the scroll deltas from trackpads causes jerky scrolling behavior
by artificially amplifying the effects of very small scroll movements.
We should only round events from devices with discrete scroll wheels,
because we know the smallest unit of movement there is a single tick.
- Fix SDL2main on PSP
SDL2main was not working for PSP, because it wasn't being activated and
it wasn't unsetting the main. Besides that a debug screen being started
was causing issues with joystick input and the sceKernelExitGame calli
is no longer needed with the current PSPDEV SDK.
- Clean up imports in PSP main
- Set PSP GPU and user modes in main
- Fix exit callback in PSP main
The xdg_shell spec seems to state[1] that xdg_toplevel_configure events can
always provide a 0×0 width/height to signal that the compositor doesn't
care. SDL previously assumed the provided width/height was always valid
for fullscreen windows, and so applied it as-is.
This broke SDL applications on KDE/KWin 5.23, which now sends 0×0
configure events (and, in 5.23.3, 1×1 events for some reason), breaking
all SDL applications in fullscreen[2].

Otherwise, if one builds libSDL2_test using a new mingw but builds
the test programs using an older mingw, a link failure happens:
/opt/local/x86_64-w64-mingw32/lib/libSDL2_test.a(SDL_test_common.o): In function `printf':
/opt/local/x86_64-w64-mingw32/include/stdio.h:372: undefined reference to `__imp___acrt_iob_func'

gbm_device_get_fd() in at least some libmali versions duplicates handle.
Other implementations do not do duplication. To prevent handle leak save
drm_fd in SDL_DisplayData.
When our keyboard grab hook is installed, GetKeyState() will return 0 for the
GUI keys even when they are pressed. This leads to spurious key up events when
holding down the GUI keys and the inability to use any key combos involving
those modifier keys.
This fixes a compile warning — and possible invalid memory read —
introduced in 9c03d255 ("Add back X11 legacy WM_NAME encodings"), which
was part of PR #5029, fixing Bug #4924.
The issue is with one of the added warnings in X11_GetWindowTitle().
Basically, the "title" variable passed to SDL_LogError() hasn't been
initialised yet: we could pass propdata in directly, but it's better to
move the SDL_LogError() call until after title is set, IMHO.
This fixes the following warning from gcc (SUSE Linux) 11.2.1:

Closes#4924.
Based on patches of the past, such as this work by James Cloos in July
2010:
d7d98751b7,
as well as code comments in the Perl module X11::Protocol::WM
(https://metacpan.org/pod/X11::Protocol::WM) and even the code to Xlib
itself, which taught me that we should never have been using
`XStoreName`, all it does is call `XChangeProperty`, hardcoded to
`XA_STRING`!
What can I say, when the task is old school, the sources are too 😂
On Win32 this list is empty and we always get controller added events. On UWP, this list is populated and we don't get controlle added events for currently connected controllers.
