A gem for creating Ruby applications with GUI interfaces by using GLFW3 for windowing and OpenGL for rendition and everything else completely custom because sanity is for the weak.
Currently experimental. Requires snow-math to be compiled with --use-float due to current use of glUniform assuming 32-bit float data. It may be prudent, later, to write a wrapper uniform function to handle this, or simply copy the UniformHash code from my gametools gem.
