XMonad ignores size hints and shrinks the client area to overlay borders on fixed-size windows, even if no borders were requested, resulting in the window client area being smaller than requested. Calling XResizeWindow after mapping seems to fix it, even though resizing fixed-size windows in this manner doesn't work on any other window manager.
When querying the keycode produced by a scancode with a certain set of modifiers, it would fall back to defaults if a key hash value with the exact set of modifiers wasn't found, which resulted in certain modifier combination returning incorrect keycodes on non-ANSI keyboard layouts. For example, querying SDL_SCANCODE_Y with the alt modifier on a QWERTZ layout returns SDLK_Y instead of SDLK_Z on most platforms, as the backends don't generate a specific entry for this key + modifier combo, so the lookup would fall back to the default ANSI layout.
Adding additional key+modifier combinations when building the keymap is one solution, but it makes an already expensive operation even more so, pushing the time needed to build the keymap into double-digit milliseconds in some cases due to the large amount of key combos that need to be queried, most of which are redundant.
Instead, falling back to searching through the shift levels for the given modifier state when querying the keymap will ensure that the most appropriate keycode is returned. This does add some overhead to lookups if the key doesn't have an entry with the exact set of modifiers, but it is minimal as hash table lookups are an inexpensive operation, and unnecessary lookups are avoided. In my own testing of an optimized build, the difference between best-case and worst-case performance (the latter of which is highly unlikely in real-world usage) is only a few hundred nanoseconds. Additionally, the unmodified keys are queried when pumping events, so there is no additional overhead in that case.
Windows seems to implicitly enable IME text input on windows created while an IME is active, which causes the IME suggestion window to pop up when keys are pressed, even if a client never explicitly enabled it. Ensure that IME support is initially disabled on new windows; SDL will enable it at a later time, if required.
Previously, all transparent pixels were rendered as opaque due to the limitations of the 4K color mode. Replaced Gc()->BitBlt() with Gc()->BitBltMasked() and updated the mask during copy operations to correctly respect the alpha channel of textures, while maintaining good performance.
The first public beta that had a corresponding arm64 version has now
been promoted to stable, and subsequent releases will be for both
x86_64 and arm64.

This makes sure we get reliable mouse enter/exit events from the system on
older macOS releases.
Newer releases don't have this problem--my assumption is that Cocoa has a
more aggressive default tracking area installed for some newer UI feature.
For 3.2.16, we'll use the explicit tracking area on older macOSes only, but
I'll remove that check in revision control for newer OSes and see what
happens.
Fixes#12725.
Use the proper types for xkb mod masks and layout indices, rename the mod masks to reflect that they are bitmasks and not indices, and use the 'layout' nomenclature instead of the deprecated 'group' nomenclature.
xkbcommon 1.10.0 declared certain modifier names to be deprecated, and the current plan is to remove them in 1.12.0. Use the new recommended names and modifier mask retrieval function when building against version 1.10.0 and higher.
