thirtyflightsofloving/missionpack/g_newai.c
Knightmare66 3672ea6be8 Added cvars ui_new_textfield and ui_new_textbox to toggle drawing text fields and text boxes with new images and font-based tiles.
Improved Tactician Gunner prox mine detection in missionpack DLL.
Implemented Zaero modifications (can be pushed off ledge) to exploding barrels in missionpack DLL.
Changed incomplete vector parsing check in ED_ParseField() to a warning instead of an error in all game DLLs.
