Panel scrolling bugs (Lazarus) / Missing Focus Rect on Tabbed Links (Delphi)

[GoogleCodeExporter]

Which steps will reproduce the problem?
1. Lazarus 1.1 + THtmlViewer svn rev.401 + Windows XP, Windows 7
2. Compile and run attached project

3. Scroll document by scrollbar for reproducing first bug - panel is not 
scrolled (laz_scrolling_by_scrollbar.gif)

4. Re-run application
5. Scroll document by [TAB] key for reproducing second bug - panel is not 
scrolled and other deviations (laz_scrolling_by_tab.gif)

Bug with scrolling by [TAB] reproduced on Delphi 2010 too, but in addition 
FocusRect on links is not showing.

r409 fixes the scrolling issues. 

Admittedly it is flickering. More effort is required to get a good solution, 
but at least it is much better than before.
