           Summary: Error in documentation for tcMod transform
           Product: GtkRadiant
           Version: 1.1-TA
          Platform: All
        OS/Version: All
            Status: NEW
 Status Whiteboard:
          Severity: normal
          Priority: P2
         Component: web
        AssignedTo: ttimo@idsoftware.com
        ReportedBy: jbaxter@lemur.stanford.edu

Just ran into this again so I thought I'd submit it.  This error is present in 
every version of the Shader Bible, including the one distributed with the 
editor and online at qeradiant.com.  (BTW, if you go to gtkradiant.com, there 
is no "Users Manual" link in the sidebar... probably should be.)

So... in the part on tcMod transform, this equation is shown:

T' = t * m01 + s * m11 + t1

The first two constants are switched; it should really read

T' = s * m01 + t * m11 + t1
