ObjC: Add interface for injecting custom shaders in video views This CL adds a way for external clients to inject their own OpenGL(ES) shaders to RTCEAGLVideoView/RTCNSGLVideoView. The shader interface takes textures as arguments, and not RTCVideoFrame, so that implementations only has to deal with actual OpenGL rendering, and not converting frames into textures. This CL also moves the internal shader code around a bit. The current RTCShader interface with the implementations RTCI420Shader and RTCNativeNV12Shader are removed. RTCEAGLVideoView and RTCNSGLVideoView will be responsible for uploading the frames to textures instead using the helper classes RTCI420TextureCache and RTCNV12TextureCache. They then call the shader implementation with these textures. The rendering code that used to be in RTCI420Shader and RTCNativeNV12Shader have been merged into one RTCDefaultShaderDelegate class.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
