Raw Normal View History

Reworked 2D pic drawing using a new, merged R_DrawPic() function. Moved old pic drawing functions to r_draw_removed.c. Added new SCR_DrawPic() variants in cl_screen.c. Added new graphics for text fields and sliders in menus. Improved mouse interaction for menu sliders. Added resettargets developer command to default Lazarus and missionpack DLLs. Added hint_test developer command to missionpack DLL. Fixed freeze developer command in default Lazarus and missionpack DLLs so it can be used more than once. More tweaks to Tactician Gunner prox mine safety checks in misssionpack DLL.
