OpenGL optimalisation

The implementation as it is work perfectly fine. However it is possible to make some significant optimalisations.

High level overview

• Reimplement colors
• Refactor arrays
• Ignore vertices outside of the viewport
• Ignore vertices smaller than half a pixel
• Precompute Matrices
• Remove depth
• Remove alpha
• Write shape optimized shaders
• Optimize the rendering pipeline
