If there are a selection already finished, should be painted,
when draw the selected area. Redraw can be triggered by events
externals to what the user do, like canvas scroll due to
open or close subtoolbars,
or a window opened over the canvas (ObjectChooser)

As the surface is created in draw callback, we need delay some operations
until the surface is created. The undo keep is delayed until finish draw,
then enable_undo() now only enable a flag, and a new method keep_undo()
do the real task.
This patch breaks rotation and mirror, will be adressed in another patch.

The port to cairo is a lot slower (in a xo) than using the old
primitives. Previously we was painting all the screen in most of
the operations. This patch calculate and apply clip over most of them
and add comments "TODO: clip" in the remaining.

Trace code was used by brush, eraser and rainbow tools.
Was replaced in the brush and eraser tools, due to artifacts
when the alpha is not 1.0
The rainbow tools continue using the old code (renamed to _old_trace)

The stored images are pixbuf instead of pixmaps now.
Created two methods _surface_to_pixbuf and _pixbuf_to_context
to copy from/to pixtuf/surfaces because the code was used
in a few places.
enableUndo was renamed to enable_undo too and unneded parameters
removed.

Copy, paste and move operations are implemented.
NOTES:
* Change size of selection is not implemented in this patch.
* A refactoring was done to do the code easier to understand.
Previously, the Area.selmove was used to check if a selection is
in progress. Now only to check if a area is being moved.
A selection is detected using Area.is_selected().
The propery selmove now is private _selmove.
The selected area now should be obtained using Area.get_selection_bounds(),
and not using Area.orig_x, Area.orig_y and the selection size.
This properties should be removed after finish refactoring.
The property Area.sel_get_out was removed.

Brushes and shapes are working.
NOTES:
* The pixmaps used as canvas has been replaced by ImageSurface and cairo context.
* All the gc with tool properties were removed.
* The variables needed by the freeform and rainbow were moved from Area to Desenha
* The freeform code was simplified.
* The heart is draw using cairo curves and is a little different than before.
* I am using cairo_stroke_color and cairo_fill_color values in the tool dict
to enable compatibility while the port is done, later will be unified.
I am setting this color with a fixed alpha of 0.3 to display artifacts
if we want enable alpha in the future. It's only for test at this stage.
* The code used to display the polygons (triangle, trapezoid, arrow,
paralellogram, star, polygon_regular) was simplified calling a method
_draw_polygon witha array of points.
PENDING:
* All the clipboard operations.
* All the efects.
* Text
* Bucket
* Stamps

The user can select a part of the image to use it like a stamp.
When the stamp is selected, can change the size, and use it to draw.
