Encapsulates OpenGL ES 2.0 frame buffer objects. This is a simple helper class which should cover most FBO uses. It will
automatically create a texture for the color attachment and a renderbuffer for the depth buffer. You can get a hold of the
texture by FrameBuffer#getColorBufferTexture(). This class will only work with OpenGL ES 2.0.
FrameBuffers are managed. In case of an OpenGL context loss, which only happens on Android when a user switches to another application or receives an incoming call, the framebuffer will be automatically recreated.
A FrameBuffer must be disposed if it is no longer needed
