* - width
|

* This is the width in pixel of the surface to copy. This may be less

* - 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
|

|
*
|
|
* 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.

|
|
* bitmap should end with RleEnd, but on the other hand, software exists
