/***********************************************************************
* X11DRV_DIB_Convert_*
*
* All X11DRV_DIB_Convert_Xxx functions take at least the following
* parameters:
* - width
* This is the width in pixel of the surface to copy. This may be less
* 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.

/*********************************************************************** /***********************************************************************
* X11DRV_DIB_Convert_any_asis
*
* All X11DRV_DIB_Convert_Xxx functions take at least the following
* parameters:
* - width
* This is the width in pixel of the surface to copy. This may be less
* 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.
