This is a helper class for stencil creation.
It is a raster with infinite resolution in the X direction (approximately, since it uses double precision). Lines that represent polygon edges can be drawn into this raster, and then filled given a tolerance.

Destructor.

Reset the raster to its original state, but keep the same whole extent.
Pre-allocate the specified 1D allocateExtent, which must be within the whole extent.

Insert an x point into the raster.
If the y value is larger than the y extent, the extent will grow automatically. The parameter i indicates which of the two internal rasters is to be used.
