Dumb-buffer pitch and size is specified by width, height, bits-per-pixel plus various hardware-specific alignments. The calculation of these values is inconsistent and duplicated among drivers. The results for formats with bpp < 8 are incorrect. This series fixes this for most drivers. Default scanline pitch and buffer size are now calculated with the existing 4CC helpers. There is a new
