Browse Source 
- 3 new points mostly done:
      - OpenGL support enabled (windows are rendered using GPU)
      - Save current screen (with overlay and so on...) with shortcut CTRL+S
      - Text rendering (with any system font, and possibility to set the style - normal, italic,... - the weight - normal, bold, ... - the color, the spacing between letters, and so on...)
