CallTryPickup will cache the item's class and pass it to HasReceived, so the latter will know what item was received even if the item has been destroyed by the time it's called.
* Feature-complete isometric mode fork.
* Dithered transparency condition tweaks.
* Dithered transparency for non-corpse monsters only (and missiles).
* SpectatorCamera vertical shift.
* Including math.h in hw_sprites.cpp to keep visual studio happy (it couldn't find M_SQRT2 definition).
* Defining MY_SQRT2 in hw_sprites.cpp to keep visual studio happy (it couldn't find M_SQRT2 definition).
* Defining MY_SQRT2 in r_utility.cpp also to keep visual studio happy.
* retrigger checks
* Have correct sprite angle-frame face the camera with orthographic projection enabled.
* Dithered Transparency now works properly on 3D floors. Moved that dither-trans flag setting code within hw_bsp.cpp to handle double-processing of linedefs. Added helper functions to FRenderViewpoint class 'bool IsOrtho()' and 'bool IsAllowedOoB()' to clean up checks everywhere in the code.
* Fixed indents. Added bbox property to subsector struct and use it instead of BSP nodes and Clippers (creating a bbox around viewpoint and checking for overlap) in orthographic mode when no fog of war is active. Turns out to be much faster. Though you need really big maps (Winter's Fury MAP01) to see a difference in fps.
* Non-linux checks don't like uint. Changed to unsigned int.
* Small change of a float to camera.zs. Ignore for testing. Should make no difference.
* Update actor.h to remain mergeable
RF2_NOMIPMAP was introduced, so I had to displace RF_ISOMETRICSPRITES to next bit.
Fixed missing teleport specials when predicting. Added rubberband limit; if too far away from the predicted position, will instead instantly snap the player's view to their new spot. Deprecated cl_noprediction; this was pointless as you'd never not want to predict your position/angles. Fixed angle targets not being backed up. Fixed oldbuttons not being set. Updated menu
Gives more useful feedback as it's not obvious which node belongs to who.
Added line breaks to network messages for cases where a large amount of players are desynced.
Default player items and shared items are no longer capable of being duplicated regardless of item flags. Shared items now give a true copy of the item. Fixed incorrect effects playing from item copies. Dropped items can no longer be shared.
