PixelPaint: Pass raw mouse event to Tools and wrap them all in a struct

Browse source 
This commit adds a Tool::MouseEvent struct, which contains events that
may be needed by tools: layer-relative, image-relative and raw (editor-
relative) event.

The raw event is used by ZoomTool to properly pan the view. This fixes
a bug which caused image to snap out of sight.
