In src/python/pathops/_skia/core.pxd we import some symbols that are not exported in the Skia include/ public headers.
This makes it hard to compile the pathops bindings with an external pre-built copy of the Skia library, without access to the skia src/ directory where SkGeometry.h is located.
In particular it's the SkConic struct and its computeQuadPOW2 method, that are used inside Path.convertConicsToQuads to compute the number of quads needed to approximate a conic given a tolerance.
