SDL_GL_GetAttribute doesn't check if a video driver has been initialized and will access the SDL_VideoDevice pointer, which is NULL at that point.
I think all of the attributes require an initialized driver, so a simple NULL check should fix it. Patch is attached.
"In particular, only one VkSurfaceKHR can exist at a time for a given window. Similarly, a native window cannot be used by both a VkSurfaceKHR and EGLSurface simultaneously"

Swift is very strict with types, so much that those of different signedness/size must be cast. Most of the defines are imported as 32-bit signed integers, while the corresponding field in a struct is a 32-bit unsigned integer. Appending a "u" would cause the defined types to be imported as 32-bit unsigned integers.
This is for corner cases where a multi-window app is activated and wants to
make a decision about where focus should go.

This lets windows know when they are dropping a mouse event because their
hit test reported something other than SDL_HITTEST_NORMAL. It lets them know
exactly where in the event queue this happened.

Clarify that grabbing the mouse only works with one window at a time; this was
always true at the system level, though SDL could previously get confused
by multiple simultaneous grabs, so now we explicitly break any existing
grab before starting a new one and document it as such.
Also track the window that is currently grabbed, and provide an API to query
for that window. This makes it easy to automate mouse ungrabbing at
breakpoints with gdb7's scripting, since the scripts can now know which window
to ungrab.
In 2.1, we should probably change this API to SDL_GrabInput(win) and
SDL_UngrabInput(void), or something.

This extension allows the user to specify whether a full flush is performed when making a context not current.
The only way to set this currently is at context creation, so this patch provides that functionality.
Defualt behaviour is set at FLUSH, as per the spec.
This patch does not contain the changes to WGL, appleGL or other platforms as I do not have access to GL 4.5 hardware on those platforms.
Full details on the use of KHR_context_flush_control can be found here:

There were several good arguments for this: it's how Windows works with
WM_NCHITTEST, SDL doesn't need to manage a list of rects, it allows more
control over the regions (how do you use rects to cleanly surround a circular
button?), the callback can be more optimized than a iterating a list of
rects, and you don't have to send an updated list of rects whenever the
window resizes or layout changes.
