                    enabled
           Product: Mesa
           Version: CVS
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal

When enables point_sprite, the points are applied with incorrect texture.

You can run the case: https://bugs.freedesktop.org/attachment.cgi?id=10950 to
reproduce this bug. Please change the macro TEX_WIDTH to 4 or 8.

The correct point should be two part: half red and half green. But with soft
rendering, the point includes three part: red at the top and bottom and blue at
the center.
