* Revert part of 37148. One FontGDI is used for fonts with different sizes. Do not cache font metrics then and instead calculate them every time when needed. It fixes spacing in menus if some application uses default GUI font with size other than 11. See issue #4106 for more details. svn path=/trunk/; revision=51356
