[Feature Request] OpenGL and OpenCL inter-op

[sumant85]

Additional context

It would help performance if we could directly pass OpenGL textures to MACE for GPU inference without first downloading those to CPU. Currently, we spend about 10% of our inference time in downloading opengl textures to CPU and pre-processing, which can be saved upon if MACE adds support for opencl/opengl interop.

@sumant85 I'm sorry to reply so late. It is a good suggestion, recently we are considering at refactoring the framework, we'll support this feature based on the new framework.
