Ufff ... what a change !

Indeed, I have seen a lot of BeginGraphics() / EndGraphics
removed ..

Very interesting. How use this tool btw ?

The speed was already very correct, but if you improve
things, nobody 
will vry

I commit it.

FYI, because of some changes I did this week end in 
salnativewidgets.cxx, some huncks didn't apply, and I
provided a new 
patch, (to be applied from sources root).

New patch =>

asalgraphics/aqua_new.diff

Note : I removed another hunck, for some control, but this
is very 
harmless (concerns cosmetics with indentation)

Just sometimes the refresh looks not complete, e.g. :

2007/new_aquasalgraphics/new_aquasalgraphics01.jpg

But this is maybe my fault...

We'll have a look, and test and test and ...   


Kind regards,

After some tries, some funky effects :

s/aquavcl01_may2007/ 
new_aquasalgraphics/new_aquasalgraphics03.jpg

Other known issues are :  black frame before every frame
drawn, Text  
in popup menus are moving from several pixels, parts not
redrawn.

Else, I must admit the suite seems to run really faster than
before ...


... to be continued

Eric


P.S. : IMHO, only one day before before to commit such
change is a  
bit short, no ?
