Originally: 2005-04-19 Carl Worth <cworth@cworth.org>

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.

-/* We want to draw a single spline approximating a circular arc radius

-
-	(R * cos(A), R * sin(A))
-	(R * cos(A) - h * sin(A), R * sin(A) + h * cos (A))
-	(R * cos(B) + h * sin(B), R * sin(B) - h * cos (B))

-   "Approximation of circular arcs by cubic poynomials", Michael

-   From that paper, a very practical value of h is:

-	h = 4/3 * tan(angle/4)
