François Gouget de02bdf37e Merged the handling of 15 and 16 bits X server depths. 
Use the masks to distinguish between 15 and 16 bits.
Check the masks better and call generic code if they are not
supported directly.
Changed the 'notsupported' traces from FIXMEs to WARNs.

* than the full width of the image.
* - height
* The number of lines to copy. This may be less than the full height
* of the image. This is always >0.
* - srcbits
* Points to the first byte containing data to be copied. If the source
* surface starts are coordinates (x,y) then this is:
* image_ptr+x*bytes_pre_pixel+y*bytes_per_line
* (with further adjustments for top-down/bottom-up images)
* - srclinebytes
* This is the number of bytes per line. It may be >0 or <0 depending on
* whether this is a top-down or bottom-up image.
* - dstbits
* Same as srcbits but for the destination
* - dstlinebytes
* Same as srclinebytes but for the destination.
*
* Notes:
* - The supported Dib formats are: pal1, pal4, pal8, rgb555, bgr555,
* rgb565, bgr565, rgb888 and any 32bit (0888) format.
* The supported XImage (Bmp) formats are: pal1, pal4, pal8,
* rgb555, bgr555, rgb565, bgr565, rgb888, bgr888, rgb0888, bgr0888.
* - Rgb formats are those for which the masks are such that:
* red_mask > green_mask > blue_mask
* - Bgr formats are those for which the masks sort in the other direction.
* - Many conversion functions handle both rgb->bgr and bgr->rgb conversions
* so the comments use h, g, l to mean respectively the source color in the
* high bits, the green, and the source color in the low bits.
