ANNOUNCE: SDL_gui 0.10.1

This is the second release since converting the library to C++,
but the first release that was actually announced :slight_smile:

The original C interface is mostly intact, but will go away at
some point.

Some notable additions:

  • can overlay gui elements on top of existing screens, including
  • cross compiling works nicely
  • SDL initialization is handled in application code now, to allow
    custom init.
  • new and improved demos
