  2. [feature] Support tolerances for QgsRasterTransparency pixel values 

    Allows pixels with color components just outside of the specified

Useful for photographs or compressed rasters where a range of color
values must be made transparent

  7. [api] Split tolerance into separate values for red, green, blue channels 

    Makes the API more flexible for future use. We only expose a single
tolerance value in the UI, but in future we could expose the
separate tolerances if desired (but be wary of UI bloat!!)
