Steps causing the bug to occur: 

  1. In the attachment there is a simple composition.
  2. There are also two warp datafiles, good and nogood.
  3. Good works, nogood gives me a black window.
  4. But the only difference between them is the y coordinate is inverted (*-1).

Inverting the y-coordinate

Inverting the y-coordinate also inverts the triangles' winding order, so they're facing backwards. In general, Vuo's graphics processing discards backward-facing triangles as a performance improvement (backface culling). But it doesn't really make sense to discard them in the case of Warp Image with Projection Mesh. So we'll change that.
