Patch for bug #901422 (CLAMP_TO_EDGE)

[Frank C. <dev...@ch...>]

Here: <http://chaoticbox.com/quesa901422.zip> is a small patch that  
checks for CLAMP_TO_EDGE and uses it when available for texture shaders  
that have a kQ3ShaderUVBoundaryClamp setting. The original report is  
here:  
<http://sourceforge.net/tracker/index.php? 
func=detail&aid=901422&group_id=45158&atid=442052>

On a similar note; Is there a better way to submit patches? Do you guys  
prefer some sort of diff tool output? If so, please let me know...

Thanks,
Frank.
