2022-09-01qcam: viewfinder_gl: Take color space into account for YUV renderingLaurent Pinchart
Update the YUV shaders and the viewfinder_gl to correctly take the Y'CbCr encoding and the quantization range into account when rendering YUV formats to RGB. Support for the primaries and transfer function will be added in a subsequent step.
