c7ff4c2ed6 Canvas zooming (#716)
* Zoom icons.

* Actions.

* Min zoom of 0 does not make sense.

* Zoom logic.

* Modify how zoom affects selection rendering.

* More precise scrollbar dimensions.

* Adjust elements visibility and scrollbars.

* Normalized canvas width and height.

* Apply zoom to resize test.

* [WIP] Zoom using canvas center as an origin.

* Undo zoom on `getScrollBars`.

* WIP: center zoom origin via scroll

* This was wrong for sure.

* Finish scaling using center as origin.

* Almost there.

* Scroll offset should be not part of zoom transforms.

* Better naming.

* Wheel movement should be the same no matter the zoom level.

* Panning movement should be the same no matter the zoom level.

* Fix elements pasting.

* Fix text WYSIWGT.

* Fix scrollbars and visibility.

c2a3b67ccc Fix scrollbar (#735)
The computation was not correct. I'm not really sure how it used to work but it was not taking into account the dimensions of the scene so it was wrong.

The new algorithm is computing the scrollbar such that it's the position of the viewport in relationship to the bounding box of the viewport and all the elements.

Fixes #680

e1ed40be65 Fix exported size when drawing to the left (#575)
If you scroll and draw to the left of the origin, when you export the scene, there's a weird whitespace on the right. This is because we do the min() computation starting at 0 and not -Infinity

This also fixes pasted elements and scrollbars.
