a9b87ee201 Fixed warning C28159: Consider using 'GetTickCount64' instead of 'GetTickCount'. Reason: GetTickCount overflows roughly every 49 days.

7c71e72193 SDL_render: Call InvalidateCachedState to initialise some of driverdata values (eg '*_dirty' to 1). 
At the earliest place, immediatly after driverdata is set.
(Doing it in SDL_render.c, after creation, would be too late, because there're renderers that already use/change those values in the CreateRender() function).

447b508a77 error: SDL's allocators now call SDL_OutOfMemory on error. 
This means the allocator's caller doesn't need to use SDL_OutOfMemory directly
if the allocation fails.

This applies to the usual allocators: SDL_malloc, SDL_calloc, SDL_realloc
(all of these regardless of if the app supplied a custom allocator or we're
using system malloc() or an internal copy of dlmalloc under the hood),
SDL_aligned_alloc, SDL_small_alloc, SDL_strdup, SDL_asprintf, SDL_wcsdup...
probably others. If it returns something you can pass to SDL_free, it should
work.

The caller might still need to use SDL_OutOfMemory if something that wasn't
SDL allocated the memory: operator new in C++ code, Objective-C's alloc
message, win32 GlobalAlloc, etc.

Fixes #8642.

daa38dc793 touch: Replace GetNumTouchDevices/GetTouchDevice with a single function.

instead of an index, too.

dfee3f9e92 render: Replaced SDL_RenderFlush with SDL_FlushRenderer. 
This uses the same `SDL_VerbNoun` format as the rest of SDL3, and also
adds stronger effort to invalidate cached state in the backend, so cooperation
improves with apps that are using lowlevel rendering APIs directly.

Fixes #367.

7e86b6aef2 Win32: Fix keymap for keyboard layouts that can print UTF-16 surrogates and ligatures 
Old implementation with `MapVirtualKey(..., MAPVK_VK_TO_CHAR) & 0x7FFFF` simply returned `A`..`Z` for VK_A..VK_Z and
completely useless <U+0002 START OF TEXT> (`WCH_LGTR 0xF002` without high-order bit) in case of ligature.

See https://kbdlayout.info/features/ligatures for a list of affected keyboard layouts.

1b284cd415 X11 pen detection: fix misclassification due to improper init 
xinput2_device_is_pen() was testing against default-zero values
in the X11 Atom cache on at least the first round of
detections, leading to imprecise detection.

The patch fixes two aspects of initialisation:

1. Ensure that the selector cache is always initialised in
xinput2_device_is_pen().

2. Ensure that all X11 Atoms used in SDL_x11pen.c are instantiated if
missing. This ensures that they are never None and avoids potential
failures to detect hot-plugged tablet devices.

Acknowledgements: @tilman3 for narrowing down the issue and an
initial fix

42a8139fd6 render: Clip bresenham lines against a real viewport thing. 
You can't just use renderer->view->viewport, because it might be (0,0), -1x-1.

I _think_ this is more right?
