QPalette for widgets which are both disabled, and belong to an active window

Currently, there is no color group in QPalette for widgets which are both disabled, and belong to an active window. The current behavior prefers the 'disabled' group over the 'inactive' group. Since both states are boolean, there is a missing state, inactive+disabled. This causes problems if the inactive palette (the background especially) is different from the disabled palette. KDE4 allows the inactive palette to be different (the default setting will probably be "darker"; the Oxygen style will require some form of palette effect to distinguish active and inactive windows), which results in disabled widgets being incorrectly bright in inactive windows.
