Log Message:
	Fix for bug #4172:

	* src/cairo-pattern.c: (_cairo_pattern_shader_gaussian),
	(_cairo_image_data_set_linear), (_cairo_image_data_set_radial):
	Use _cairo_fixed_to_double and _cairo_double_to_fixed when converting
	between double and 16.16 fixed point.  These functions round nicely,
	and solve some inconsistencies in rendering between my PPC and x86
	machines.  Thanks to Owen Taylor for suggesting the fix.

	* test/gradient-alpha-ref.png:
	* test/linear-gradient-ref.png:
	* test/text-pattern-ref.png: The above change does affect linear
	gradients slightly, but it seems worth it.  Update the reference
	images to follow.
