Andrea Canciani	6155348966	default-context: Do not allow restoring pushed gstates ... The brackets defined by push/pop and save/restore are independent ad should match properly. This means that cairo_push()-ed gstates cannot be cairo_restore()-d and cairo_save()-d gstates cannot be cairo_pop()-ed. Fixes group-state.	2011-07-30 09:51:02 +02:00
Chris Wilson	b132fae5e8	clip: Rudimentary support for clip-polygon extraction ... Step 1, fix the failings sighted recently by tracking clip-boxes as an explicit property of the clipping and of composition. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>	2011-07-19 21:14:34 +01:00
Chris Wilson	2458120dee	pattern: Add observer hooks ... In order for custom context to automatically track when a pattern is modify after being set on the context (and before it is used in an operator), we need for there to be a callback when the pattern is modified.

Chris Wilson	83bfd85a13	Implement cairo_backend_t ... Allow a backend to completely reimplement the Cairo API as it wants. The goal is to pass operations to the native backends such as Quartz, Direct2D, Qt, Skia, OpenVG with no overhead. And to permit complete logging contexts, and whatever else the imagination holds. Perhaps to experiment with double-paths? Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>	2011-07-15 11:05:19 +01:00
