OGL

Compilation: Windows - compile by running .\make.ps1 in PowerShell. Linux - compile by running make.

Ideas:

* Texture binding operations

* Text rendering
* Console and runtime commands

* Instanced rendering 
* Particles and visual effects

* Lighting(ambient, diffiuse, specular)
* Specular mapping

Warnings:

* GLSL compiler can optimize away redundant code, which may cause unreachable uniform variables
