Subject: [PATCH] mdi: fix drawing the MDI client area when creating children.

When there is an MDI child in the maximised state (covering the
entire MDI client area), and a new MDI child is created the MDI
windows are restored. In this case, the MDI client area needs to
be redrawn so that the workspace is shown.
