mappings yet, that's a good way to test this functionality. * Turns out the directory of the mappings must be known already - they should be added automatically, but I've added them manually for now (which is okay for the default system directory). * Having more than one style with the same family in the mappings didn't work as planned - it now does. * On my current system, time spend in the font manager constructor went down from 1.5 secs to around 12000 usecs (and I have only a moderate number of fonts installed, or so I thought - looks like the mappings were a good idea :-)) - and that directly cuts down the boot time. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15580 a95241bf-73f2-0310-859d-f6bbb57e9c96
