#300 OpenGL backend

[UltraBas]

In OpenGL mode, graphics command don't work.

Is it possible to implement an OpenGL renderer (by rendering fbgfx output on a texture, and then displaying the texture on the screen?). This would allow to easily mix 2d and 3d graphic (i.e. using OpenB3D, or other libraries that render on OpenGL, to make a game and FreeBasic 2d commands to display score and GUI).

Also, it would allow using GLSL shaders for post-processing the FBGFX graphic.
