Added new "--center" option that causes the source display to be centered without upscaling in the destination display (letterboxing). This is allows to record FullHD but without having to downscale the raw footage later in some scenarios where the original 7" Touch LCD footage is needed with the 800x480 resolution. Letterboxing is necessary, as otherwise some HDMI recorders would refrain from recording such low resolutions.
