Bug Description

gDEBugger shows that glBufferData makes up about 5.38% of all openGL function calls, and for simple usecases like playing video, its often the same data over and over again. Along with the use of GL_STATIC_DRAW vertex buffers, this means that we're constantly uploading redundant data to the GPU
