[Tuxmath-devel] Multithreading for rescaling title screen and menu items

[Wenyuan G. <guo...@gm...>]

Hi all,

As promised, I have coded a new feature that enables multithreading
when it rescales title and menu during an in-game resolution change.
As before, the game changes to the new resolution (either fullscreen
or windowed) instantly. But when the user quits to the menu, it is
usually instantaneous too, provided the worker thread has gotten
enough time to finish (usually 2s).

However, resolution change when in-menu still inevitably takes 2s, due
to the serial nature of the process.

The git repository has been updated. Please feel free to try it out!

Cheers
Wenyuan
