Opportunities for optimization (startup)

[Jan Wassenberg]

• tc_CalculateVariationKey: 1.72362 s (8010x): graphics/objectmanager.cpp

TODO (for some efficiency): use the pre-calculated choices for this object, which has already worked out what to do for props, instead of passing the selections into BuildVariation and having it recalculate the props' choices.

• Gamesetup/config.cpp: 300ms

g_ConfigDB.Reload(CFG_SYSTEM); 216ms LoadGlobals(); 64ms

• plain_transform: 500ms flipping font texture files vertically. fix: convert them to e.g. DDS (possibly compressed, if that looks ok?!) same thing for art/textures/particles/sprite cursors also require runtime conversion. ironically enough, being DDS means they have to be converted back to TGA's BGR ordering (required by Windows for cursors)

• CSimulation init: 5000ms

[more will be added as they are found]
