State of initWithFocusedViewRect: on libart backend

[Fred Kiefer]

I am thinking about improving the way we create image cursors. The 
current code wont work with a lot of iamge formats. Actually it does 
only work with RGBA, non-planar, 8 bit, not padded, non scaled bitmap 
image representations. To improve on this I would like to convert the 
image to a bitmap image first with:

{
  NSSize size = [image size];

  [image lockFocus];
  rep = [[NSBitmapImageRep alloc] initWithFocusedViewRect: 
NSMakeRect(0, 0, size.width, size.height)];
  [image unlockFocus];
}

which should work fine on the xlib backend (the window backend doesn't 
even support iamge cursors for the moment). The most simple way to do 
this is to use the conversion on all images, but for this backart would 
need to implement GSReadRect:

Alex, do you see a chance to implement this? Adams implementation for 
xlib looks pretty forward to me.

While I was looking at the code in backart, I had some totally unrelated 
ideas. What about unifying the unmaintained string drawing code, that is 
all the other string showing Postscript commands apart from DPSshow? We 
could just move them up to GSGState and implement them via a 
DPSshowString:length: primitive. Not that anybody is using this methods 
now, but at least we wont have parts of them scattered everywhere in the 
backends.

And there my next question came up (I shouldn't be reading this much 
code): What is backart doing in [FTFontInfo 
drawString:at::to:::::color::::transform:] to convert from UTF8 to 
Unicode? Or more specific, in which regard is this conversion different 
from the one implemented in GSToUnicode in Unicode.m?
