e9c7cfb165 Revert "Use rounded results for expanding values to 8-bits" 
This reverts commit ba5be7af74.

We actually want to use high bits and replicated low bits, to match SIMD value expansion

8df057fafc iostream: Properly support the "x" mode for SDL_IOFromFile() 
The "x" mode for `fopen()` (open file only if it doesn't exist) used to
be a glibc-exclusive extension, but was later standardized in C11, and
is now also implemented as part of every other widely-used libc:

	* musl: https://git.musl-libc.org/cgit/musl/tree/src/stdio/__fmodeflags.c?id=0ccaf0572e9cccda2cced0f7ee659af4c1c6679a
	* Android Bionic / OpenBSD: 731631f300/libc/upstream-openbsd/lib/libc/stdio/flags.c (86)
	* Apple / FreeBSD: 63976b830a/stdio/FreeBSD/flags.c (L91-L92)

As a result, "x" has already been working on all our automatically
tested platforms that implement `SDL_IOFromFile()` via `fopen()`. So
all we'd be missing for proper support is a Windows implementation
using `CREATE_NEW`, and the documentation that this mode exists and is
intended to work.

ce1175724a win32: Don't overwrite a programmatically set window size with old data 
While in a modal loop, the size in WM_WINDOWPOSCHANGING/WM_WINDOWPOSCHANGED may only be updated if the window is being resized interactively. Set the SWP_NOSIZE flag if the size hasn't changed from the last move/size event, or a size set programmatically may end up being overwritten by old size data.

8fda4231cf wayland: Optimize the legacy key level fallback function 
When iterating over the keymap entries, a valid xkb state object has already been allocated, so use that instead of allocating/destroying a new state object for every lookup, which avoids a calloc/free operation inside libxkbcommon. Any state set by the level lookup function will be overwritten with valid state after keymap iteration has completed.

Frank Praznik
2c02e6f8bb wayland: Restore valid state information when building keymaps 
The spec doesn't guarantee that a modifier event won't arrive before a keymap event, or that it will always be sent after a keymap change if the modifiers and layout index haven't changed, so restore any valid state after allocation when building a new keymap.
