SKAsyncGLViewController - replacement for classical GLKit stack (GLKView + GLKViewController). 

It renders all your stuff in background GCD-thread and shows result on main thread.

**OpenGLES2/OpenGLES3**

### Usage

After installation, inherit your viewController from SKAsyncGLViewController and implement these methods:

:wrench: Select your API version by returning EAGLRenderingAPI value here (default is kEAGLRenderingAPIOpenGLES3)

- **- (EAGLRenderingAPI)getApi**

- **- (void)setupGL** 

:wrench: This one for setup your GL - create buffers/load shaders/etc here.

- **- (void)drawGL:(CGRect)rect**

:black_nib: :pencil2: Here you draws all your stuff!

- **- (void)clearGL**

:x: This method calls when your vc's view removes from superview. So here you have to clear all your gl stuff (delete buffers .etc)

You can access framebuffer, renderbuffer and background queue through view's properties.
