xserver/include picturestr.h,1.29,1.30

Committed by: lars

Update of /cvs/xserver/xserver/include
In directory gabe:/tmp/cvs-serv16798/include

Modified Files:
	picturestr.h 
Log Message:
Add support for gradients and solid fills to Render. 

Changed the semantics of the Convolution filter a
bit. It now doesn't try to normalize the filter
values but leaves this to the client. This gives
more reasonable behaviour in the limit where the filter
parameters sum up to 0.
