Fixed an image resizing bug. Tweaked a couple of methods in KeyMappingEditorComponent and TableListBox to return references instead of pointers. Changed Component::contains() to take a Point rather than raw coordinates. Modernised some UI classes internally. Extended some internal graphics classes to handle affine transforms.
