OpenGL renderer with asynchronous loading of assets (experiment).

The application first starts with rendering quad without texture.

After 1 second a load request is dispatched tocontent loadingsystem, which asynchronously loads file from disk, decodes it anduploads image data to GPU without blocking or stopping the mainthread, so the OpenGL application continues to run smoothly(without any fps drop) even when data is being uploaded to GPU.

The whole thing is based on creating another OpenGL context inuploader thread, which shares resources with themain renderthread. The communication is synchronized using GLfences.
