- mutualized shape tools common code in a ShapeTool class
- when holding shift and drawing a frame, the ratio is preserved
- selection and shape tools now support the mouse to leave the drawing
area
- shape tools can go 'outside' the drawing canvas
- Frame set/getPixel now check the pixel is in range instead of crashing
Issue was coming from the cached frame renderer.
During the window resize, we update the displaySize of the frame renderer,
regardless of the fact that the dimensions changed or not.
The setDisplaySize triggers a destruction of the canvas. But the
CachedFrameRenderer will render the frame only if it detects a change. In
this case, setDisplaySize has been overrided in CachedFrameRenderer to
skip any processing if the dimensions didn't change.
This behavior could be actually done in the FrameRenderer itself, but
since this is crucial to the CachedFrameRenderer behavior, I prefer to
keep it in this class.
Alternatively, could implement a way to discard caches of
CachedFrameRenderers from the outside.
Mousemove events do not have the correct button information
Need to keep the state of which button is clicked at which moment
This was actually the initial implementation ...
But I removed it because I couldn't remember why we did this in the
beginning.
Added lots of 'warnings' in comments, but won't be safe until we get good
integration tests.

"What if multiple buttons are pressed during mouse move? And how does the
integer field (button) indicate that no button is pressed? I think this
should be wontfix -- if people need button information during mouse move events
we need a new way of getting it (buttonSet), not the same way it works for click,
etc."
