Fix for the stack overflow

This patch would fix the stack overflow, but the pattern in the PoC pdf file
would still take an enormous amount of time to rasterize, given the current
approach used in cairo.

Backward rasterization could probably help handling such degenerate patterns
more efficiently, but the peculiar ordering of the mesh layers makes their use
nontrivial.

What is the best way forward? Is this patch sufficient?
