A GUI::Widget can now set an optional content margin (4x0 by default.) Pixels in the content margin will be ignored for hit testing purposes. Use this to allow frame-like widgets (like GUI::Frame!) to ignore any mouse events in the frame area, and instead let those go to parent. This allows GUI::Splitter to react "sooner" to mouse events that were previously swallowed by the child widgets instead of ending up in the splitter. The net effect is that 2 more pixels on each side of a splitter handle are now interactive and usable for splitting! :^)
