A simple playground for my OpenGL experiments

• Finish this readme
• Remove GLFW dependency
• Configure Makefiles for building on Windows, Linux

• Create global "renderer info" class (screen res, etc)
• Create more robust model loader class
• Create scene class (drawing manager)
  • efficient renderable scenes
• Create material shader library
• Make ui manager
  • Text area
  • icons
  • status bars
  • static elements
• Modify printer class for more flexible texture atlases
• Maybe create a "render font" file format
• Modify Printer::print() to be variadic so I can stop snprintf-ing

• Formats:
  • BMP
  • TGA
  • TIFF
  • PNG
• Make texture object interact with FBO object
