It's probably because memory allocations are too expensive on your system. The
rasterizer and everything else is designed in such a way that it minimizes the
allocs and reallocs. The rasterizer allocates memory in chunks and never
releases it until you destroy it. The path_storage and conv_stroke do the same.
