Sorry (Re: Found!!! Re: [Q[ Text Drawing in ART backend...)

All my trouble is because I've used subpixel rendering option... If I turn this off, all text
display is not problematic... sorry for trouble... :-)

I've found what part is responsible for problematic string drawing....
It's related with sbit font drawing in drawGlyphs:.... method. If sbit_use is turned off, every font(yes, shape itself is worse than sbit_use case..) is
correctly drawn. Now, I'm trying to find way to work around this....

Hi,

I've found that drawString:... and drawGlyphs: in ftfont.m in art backend is correct. And also found that these methods are not used for every text drawing... So, my conclusion is that drawXXX methods are correct and I have to search other places to solve or find a clue for text drawing problem... Further search let me know that NSStringDrawing.m in GUI is responsible for it. Any documentation for this text drawing mechanism available ? And here comes another trivial question; do most people using GNUstep just uses plain x11 backend, instead of art ? So they are not aware of text drawing problem ? Or is it that hard to resolve this problem? On my system plain x11 backend is too slow...

Thanks in advance.
