Bug #: 30923
           Summary: Gigasoft ProEssentials graphing component clips
                    improperly
           Product: Wine
           Version: 1.5.6
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2

    Classification: Unclassified

A real app that uses Gigasoft's graphing dll has a clipping problem.
I was able to reproduce the clipping problem with a small C
program which uses the DLL to create a graph containing two horizontal lines, 
one of which is outside the graph's clipping region and should not be drawn.
On Windows Vista, the graph draws properly, and only the dashed line
is visible.
On Wine, the solid blue line is also visible, even though it should be
clipped away.
