When macOS runs under a virtual environment, it is possible that
MTLCreateSystemDefaultDevice() does not succeed.
Not checking this failure results in a crash down the road.
This change allows to skip GPU renderer and use an adequate fallback.

Wayland gives no feedback to windows regarding whether a minimize request was successful, so we would universally send the minimize event and assume that the request succeeded.
Check the window manager capabilities, if available, for whether window minimization is supported, and don't send the minimized event in the case that it is unsupported.
Excessive resize events generated during interactive window resizing can cause applications to lag, severely in some cases. Throttle interactive resize events to once per frame callback interval.
- make all of function pointers static
- make EGLint context_attribs[] static
- comment out unused function pointer ov_wglGetCurrentContext
- remove unused SDL_DisplayMode openvr_dm_default
- move SDL_VideoDisplay openvr_vd_default to OPENVR_VideoInit()
context and eliminate its C99 initializers
- replace atoi() calls with SDL_atoi()
- replace atof() calls with SDL_atof()
This is already done on win32, however, other platforms were left in a state of limbo if a drop operation began, then never completed due to the drop leaving the window.
The window content scale may change independently of the display it is on if scaling or accessibility features are involved, so query it directly from the backend instead of inferring it.
This is an X11 error catcher that lived for the entire life of the program,
which causes problems in itself, but it also tries to make calls into Xlib,
which would cause further panics.
It's goal was to reset video modes if the app was going down, but it often
failed to do so, and caused potentially avoidable crashes instead.
Fixes#7975.
The text-scaling-factor setting is not useful, now that we watch the
Xft/DPI and Gdk/WindowScalingFactor XSETTINGS keys; on the contrary, it
is problematic in mixed environments with both the KDE and GNOME
portals, as they end up stepping on each other's toes, and we end up
with the wrong scaling factor value.

This is sent when the device is lost and can't be recovered.
Also fixed the vulkan renderer so it returns errors appropriately and will log and break if debug mode is enabled.
This fixes the following sequence:
* Press mouse button down
* Alt-tab away from the window
* Alt-tab back to the window
* Release mouse button
