Add cairo_stroke_preserve, cairo_fill_preserve, and cairo_clip_preserve. Rip the path out of cairo_gstate_t. Add path to cairo_t. Bring in most of the path code that used to live in cairo-gstate.c Move arc generation code into its own file. Accept path+ctm_inverse+tolerance instead of gstate. Absorb flattening and device space->user space conversion that used to be in _cairo_gstate_intepret_path. Prefer cairo_fixed_t parameters over ciaro_point_t for cross-file interfaces. Track changes in _cairo_path_fixed interfaces. Port to use cairo_fill_preserve rather than cairo_save/cairo_restore which no longer work for saving the path. Remove get and set of current point since it is no longer affected by cairo_save and cairo_restore. Add get and set testing for cairo_matrix_t.
