Michael Natterer 0add37a6cc app: remove GimpDisplayShell parameters from all GimpCanvasItem vfuncs
and get the shell from gimp_canvas_item_get_shell() if needed.  Remove
some cairo_translate() that didn't have any effect and were leftovers
from a very early canvas item code.

Michael Natterer 64c929a1d1 app: add an own GimpCanvasItem API for transforming coords
and use it in all subclasses. Removes all gimpdisplayshell-transform
dependency from all item implementations.

Michael Natterer 60d24b4c04 app: get rid of #ifdef USE_CAIRO_REGION almost everywhere
get replaced by GDK region functions and use the cairo region
functions unconditionally all over the place.

Michael Natterer 479082075b app: use cairo_region_t for canvas items if cairo >= 1.10 is available
This is a gross hack that typedefs around between GdkRegion and
cairo_region_t and has some evil #ifdefs. This is going to die
immeditately once we can depend on cairo 1.10.

Michael Natterer b74811324a app: don't use PROJ_ROUND() for pixel-adjusting canvas item drawing
When PROJ_ROUND()ing e.g. 3.8, it ends up at 4, then we added the 0.5
offset to draw a nice cairo line in the middle of the pixel,
effectively drawing a line that's meant to be at 3.8 at 4.5.  Instead,
we now use floor(x)+0.5 now which snaps the above example to 3.5.

Also, calculate arcs like we calculate rectangles (transform the arc's
bounding box and pixel-align that, then recalculate the center), so
arcs properly align with rectangles.

Michael Natterer d3f19baf0d app: remove "shell" parameter from GimpCanvasItem's public APIs
because each item has a shell now. Keep the parameter in the virtual
functions though because that saves a lot of code in the subclasses.

Michael Natterer 201bfe3e25 app: add a "shell" property to GimpCanvasItem
and pass it to all constructors. The GimpDisplayShell is needed
because items are going to become more powerful soon.
