From 8f3eb6051c0465923d6694bd0f0b6dc5bb51cbe3 Mon Sep 17 00:00:00 2001 From: npm Date: Fri, 11 Nov 2016 17:16:23 -0800 Subject: Remove IFGAS_FontMgr and clean up (the renamed) CFGAS_FontMgr a little. IFGAS_FontMgr is an interface only for a class only defined on Windows, plus a class only defined for non-Windows. I'm removing the interface, renaming the class to have the same name in both cases, and cleaning up a bit of unused methods.
