Fix related to #36319: restore SDL_VIDEODRIVER=dummy environment variable, it
seems that somehow not having this is causing keyboard events to be caught by
SDL. This was removed because it broke addons that could use SDL, now set the
environment variable only temporary during SDL initialization.

This may have been causing issues with keyboard events getting missed in the
game engine, but I couldn't confirm the issue here.

Fix #36800: closing render window during render crashes, the operator would be
cancelled before the job, causing invalid access to op->reports in the job thread.

Fix #36793: missing update on undo with proxy object that is not using a proxy group.

Fix #36783: click outside splash screen to close it would not highlight the
button under the mouse, and so clicking the button failed without first
moving the mouse. Similar issues could happen with popups and switching
windows.

The problem is that a notifier was being used to deactivate possible other
activated buttons, but as notifiers are delayed it could undo the correct
activation too. If anyone notices hanging tooltips or other issues after this
fix, please report them.

modifiers_isCorrectableDeformed now checks a modifier is enabled before returning true,
also check deformMatricesEM callback for modifier_isCorrectableDeformed() rather then checking modifier types.
