VESA mode: Set the viewport size correctly so the position bar does not overlay the map. VESA mode: Correctly set the size to which tiles are stretched when overview mode (F4) is selected. Both VESA and 16 color modes: Pass correct parameters to vga_userpan and vesa_userpan, so the pan keys (CTRL+arrow) work correctly. Some emulations don't report CTRL with up or down arrows, so accept CTRL-home, CTRL-page up, CTRL page down and CTRL-end. 16 color mode: Set the panning direction so CTRL-left and CTRL-right pan in the same direction as 3.4.3.
