The width of each tab is now computed from its title, independently of the other tabs. This increases the number of tabs that fit on the screen. This rewrite also fixes a bug where if the window size increased while _firstVisibleTab > 0, some tabs would become inaccessible when the scroll buttons were hidden. The layout key Globals.TabWidget.Tab.Width is now treated as minimal tab width. This is set so that the tabs fit reasonably well in lowres layouts. At the same time, this reduces the lowres scroll buttons heights to fit. This patch makes the Nintento DS hacks in TabWidget obsolete. (Hopefully! I'm not able to test.)
