Three more attempts to get metal look.

- Added a few flags for inheriting background.
     - Added wxWindow param to wxR::DrawBackground()
     - Added wxR::DrawButtonSurface()
     - Removed wxR::DrawBackground() from wxR::DrawButtonBorder()
     - Adde DrawMetal to Metal theme
  Fixed minor bug in wxGTK scrollbar.
  Changed code in wxX11 wxTLW so that startup flicker no
    longer occurs in wxFrame.
