Add text rendering using signed distance fonts

+ * @attention  MAX_BITMAPS shouldn't need to be bumped again.  With the fixed bm_release() and it's proper use even the
+ *   largest missions should stay under this number.  With the largest retail missions and wasteful content we should
+ *   still have about 20% of the slots free.  If it still goes over then it's something the artists need to fix.
+ *   For instance the Terran Mara fighter, with -spec and -glow and using the Shinepack, needs 117 bitmap slots alone.
+ *   111 of those is just for the glowmaps.  This number can be greatly reduced if the number of ani frames for another
+ *   LOD than LOD0 has fewer or no ani frames.  A 37 frame glow ani for LOD2 is little more than a waste of resources.
+ *   Future reports of texture corruption should be initially approached with content as the cause and not code.
+ *   If anything we could/should reduce MAX_BITMAPS in the future.  Where it's at now should accomidate even the
