|
|
|
|
*
|
|
|
|
* This was because the algorithm assumed that all RLE8 bitmaps end with the
|
|
|
|
* 'End of bitmap' escape code. This code is very much laxer in what it
|
|
|
|
* allows to end the expansion. Possibly too lax. See the note by
|
|
|
|
* case RleDelta. BTW, MS's documentation implies that a correct RLE8
|
|
|
|
* bitmap should end with RleEnd, but on the other hand, software exists
|
|
|
|
* that produces ones that don't and Windows 3.1 doesn't complain a bit
