EGSPlus
                Patch Enhancment for EGS Emulation
-----------------------------------------------------------

EGSPlus adds some more patches to the current EGS Workbench
Emulation. Basically the chunky mode functions introduced
with the OS 3.0 have been patched since they are real slow 
on the old EGS emulation. 

----------------------------------------------------------

EGSPlus fügt der derzeitigen EGS Workbench Emulation 
einge neue Funktionen hinzu. Grundsätzlich sind das Funktionen,
die mit dem OS 3.0 eingeführt wurden und mit Grafikdaten
umgehen können, die chunky (1 byte/pixel) organisiert sind.

Affected functions:
Betroffene Funktionen:
---------------

    · WritePixelLine8()
    · ReadPixelLine8()
    · WritePixelArray8()
    · ReadPixelArray8()
    · WriteChunkyPixels()
since Release 5 additional:
ab Release 5 zusätzlich:
    · AllocBitMap()
    · FreeBitMap()

I've them rewritten so they can now deal with direct chunky 
rastport transfers. Check out some anim programs for the result
e.g. xanim :-)
Please alos read the documentation.
----------------------------------------------------------
Ich habe diese Funktionen neu geschrieben. Sie erlauben nun
einen direkten Transfer der Daten ins RastPort. Versucht mal einige
Anim Programme wie z.B. xanim. =:->
Bitte lest auch die Doku.

History:

Release 6: Had a stupid bug on non layered operations. 
           Fixed that. IBrowse runs again now.
           IBrowse trashes some images if my cybergraphics.library
           is present. I am not sure what it is. I guess
           it has something to do with planes in fast mem (?)
           because it doesn't call any of my functions...

Release 5: Added new AllocBitMap()/FreeBitMap() Routines.
           Now it is possible to allocate Cybergraphics 
           compatible friend bitmaps (have to define 
           BMF_MINPLANES if you want to get a friend bitmap, 
           see also CyberGraphics doc).
           Plain Chunky Bitmap allocation is still not possible,
           since I do not know what value the BMB_SPECIALFMT bit has 
           ( Bit 8 ?).

           Please, also check out the latest How2UseGfxV39.lha
           in dev/src/ on how to use chunky friend bitmaps 
           (an _now_ compare cyber2egs bitmaps on the ball demo:)

           Also I fixed a bug in the WriteChunkyPixels() Function.

Release 4:
           cybergraphcics.library supports DoCDrawMethodTagList() now.

           Release 3 had still trouble with v39 systems. Was a stupid error, sorry.
           So, it should _really_ work on v39 systems now :)

Release 3:  Also included is a cybergrpahics.library that let you run
            cybergraphics applications on the EGS emulation (8 bit only
            though). WARNING ! This library is not conplete now !


Enjoy
