(note: this REQUIRES or/and/notput support in directputpixel,
this is not yet the case in the assembler versions!)
* YOffset addition moved in hlinevesa256 and vlinevesa256
because it uses still putpixel afterwards
integer; var data);" so it can be used by getimage too
* changed getimage so it uses getscanline
* changed floodfill, getscanline16 and definitions in Linux
include files so they use this new format
+ getscanlineVESA256 for 256 color VESA modes (banked)
(important note: The VESAModeInfo structure returns the MAXIMUM
number of image pages, and not the actual available number of
pages (cf. VBE 3.0 specification), that is the reason why
SetVisualPage() has so much checking).
