bug #5589. Selection area is now calculated using the inherited Reflow rather than using the calculations used for the native listbox control. Fixed varous other rendering bugs related to frame-based listboxes. bug #2797. GetSize is no longer needed in nsListControlFrame and it has been removed. Fixed frame-based combobox nsComboboxFrame so that will set it's label to the first option in the drop-down list if a default value has not been specified. Added optgroup style rules to ua.css. Opt groups now render, but there are remaining problems with selection. Modified nsButtonControlFrame::Reflow to call nsFormFrame::AddFormControlFrame. This fixes a bug where Gfx-rendered submit button's were not working. Refactored code in nsListControlFrame in preparation for supporting option groups. Refactored selection code into SingleSelect and MultiSelect paths. Removed unused code in nsListControlFrame. Removed mSelectedFrame member variable. It is no longer needed. Fixed nsListControlFrame::SetProperty so that it will toggle the selection in a single select listbox. git-svn-id: svn://10.0.0.236/trunk@30740 18797224-902f-48f8-a5cc-f745e15eee43
