Detailed Description

Fill an image region with given channel values, either returning a new image or altering the existing dst image within the ROI. Note that the values arrays start with channel 0, even if the ROI indicates that a later channel is the first to be changed.

Three varieties of fill() exist: (a) a single set of channel values that will apply to the whole ROI, (b) two sets of values that will create a linearly interpolated gradient from top to bottom of the ROI, (c) four sets of values that will be bilinearly interpolated across all four corners of the ROI.
