Detailed Description

A holder for a frame data and related parameters.

A Frame has to be set up with a FrameData which ultimately holds the pixel data using images. Input and output frames provided by the eq::Channel are set up correctly with FrameData to connect one output frame to one ore more input frames. Some Frame parameters are (input-)frame-specific, while others are set by the output frame on its data and therefore shared between all input frames.
