Description Pierre-Antoine LaFayette 2010-10-10 13:48:46 PDT 
Allocation and deallocation of GPU memory for VGPaths is expensive and should be avoided. For primitives whose segment data do not change, we can use vgModifyPathCoords to change the path.

can you wait for bug 48516 please? It's maybe possible to optimize it more after the patch there.

I believe Jakob had said that their latest OpenVG GraphicsContext code uses path caching / transforms when possible. He said they would be upstreaming that new code which would make this patch unnecessary. I had thought they would have updated the OpenVG code by now. They seemed to have abandoned their upstreaming efforts.
