The areas where the user must click to resize the image are now
scaled to ensure they do not overlap. This allows us to display the
correct cursor when zoomed out, as well as making the
borders look nicer.
Previously, the move tool would always select the topmost layer before
performing a move operation. This commit adds an option for the move
tool to always select the active layer, even if it is behind another.
It is now possible to scale the current layer using the move tool from
all four corners of the layer boundary. Previously scaling was only
possible from the bottom right of the image.
Previously, all keydown KeyEvents were accepted, causing parent widgets
not to receive them. With the addition of shortcut handling to keydown,
shortcuts were not called when the ImageEditor was focused.
This patch adds scaling function to the move tool.
When the cursor is over the lower right corner of the layer, it changes.
This is to signify that the layer can be scaled by dragging the mouse.
There is currently no preview of the scaling.
Doing a resize every time the mouse moves leads to unexpected behavior.
