SDL2 branch does not show cursor

[stephanemagnenat]

Testing the SDL2 branch here (Ubuntu 20.04 (Kubuntu), X11, Nvidia RTX 2060 super, proprietary driver version 450.102.04), I get the following errors.

• By default (with software renderer), I see no cursor, the window has refresh problem, and this on the console:

  Toolkit : can't set screen to 1280x720 at 32 bpp
  Toolkit : Can't create renderer for NULL surface
  Toolkit : Can't set screen resolution, resetting to default of 800x600
  

• With hardware (-g flag), Glob2 segfaults and the console shows the following problems:

  Toolkit : can't set screen to 1280x720 at 32 bpp
  Toolkit : No hardware accelerated renderers available
  Toolkit : Can't set screen resolution, resetting to default of 800x600
  Toolkit : can't set screen to 800x600 at 32 bpp
  Toolkit : No hardware accelerated renderers available
  

The SDL 1.2 version works fine with this setup.

After investigation, it seems that the changes to the resolution settings are broken. Code to set the resolution was added in the constructor of GraphicContext, and then the call to setRes is done which attempts to reset the resolution, this with doubtful order. I think the proper way to do this is as before, only do the window creation and resolution setting in setRes, and do it differently whether the window exists already or not.
