347f9598dc Always tread depth 24 (i.e. non alpha) as depth 32 when blitting 
When blitting we don't really care about alpha mismatches, we just copy bits
anyway.

7977a00187 spice: win32 client: fix gdi locking 
While the fix could have been more effective,
it seems like this patch stream better with the coding
logic that was there..., maybe later we will want to change
the locking into more effective way.

(There is just the primary surface to protect in reiality)

4ee6e1ac88 spice: common: gdi_canvas fix gdi objects leak 
BitmapMask was used by the draw_text function as well
therefore we need to mark from_surface = 0 if we want
it to release the boject...

(Was evil, took me few hours to understand from where
 the leak come...)

b83f707c7a Use nearest scaling for DRAW_ALPHA_BLEND since this is what win32 needs 
DrvAlphaBlend is the only current user of DRAW_ALPHA_BLEND, and its
defined to do nearest (COLORONCOLOR) scaling, not bilinear.

6b599f4147 Fix up empty region checks in canvas operations 
We rely on not passing on empty rects to the drawing operations by
checking for empty regions and exiting early. However the checks
were wrongly using pixman_region32_n_rects(region) == 0, whereas
we should be using pixman_region32_not_empty().

c22788cd26 New memory allocators that exit on OOM and handle multiplication overflow 
Every place that does a regular malloc/calloc and aborts on failure
should use spice_malloc/spice_mallo0 instead, which is leaner and cleaner.

Allocations of dynamically sized arrays can use g_malloc_n or g_new etc
which correctly handle multiplication overflow if some of the arguments
are not trusted.

82a7c42a86 Move most of the shared draw_xyz() methods from CairoCanvas to CanvasBase 
This adds a set of virtual methods for low-level operations. A subclass
can choose to implement those and let the default CanvasBase implementations
handle the highlevel stuff.

5fe1ef371c Move virtualization of canvas drawing into common/canvas_base 
Instead of having two virtualizations of the canvas we push the
virtualization into the canvas code itself. This not only avoids
the duplication of this code, it also makes the exposed API for the
canvas much smaller (in terms of exported API).

It also lets us use the virtualization to implement basic support
for operations in canvas_base which is then overridden by each canvas
implementation.

acd6262480 Fix colorkeying in pixman_utils.c 
We were masking out the alpha bit in the key color not int
the source pixel, so colorkeying didn't work when the high byte
was != 0. For instance in the shutdown dialog in XP.

46d18ce680 Replace custom region implementation with pixman_region32_t 
pixman_region32_t is an efficient well tested region implementation (its
the one used in X) that we already depend on via pixman and use in
some places. No need to have a custom region implementation.

93ae409c52 Add possibility to not invert bitmask in canvas_get_mask() 
This allows the pixman implementation to instead invert the (generally
smaller) region instead of duplicating the bitmap to invert it.

44de7fcff4 Use pixman_image_t instead of cairo_surface_t as the generic pixman container 
This allows us to use the simpler dependency of pixman outside of the
cairo backend, and it later lets us move the cairo backend to using
pixman only.
