The size constraints allow the method to choose between different resolutions if
the camera supports this. If the resolution cam't be specified (e.g. on the Mac)
then these will be ignored.
On Mac, if highQuality is false, then the camera will be opened in preview mode
which will allow the OS to drop frames if the computer cannot keep up in processing
the frames.
