\df_demos_ReplayDrawMask [ DEFAULT: 32767 RANGE: 0 TO N (mask) ] - Shows/Hides replay entities in debug modes

 1  = RP_DRAW_ID
 2  = RP_DRAW_CAM

Add the numbers to display the desired items.

Example - to show only ID numbers, Cameras, and Activation Points, use: df_demos_ReplayDrawMask 19
1 + 2 + 16 = 19

You can hide or show various replay script items while in debug mode.  This is useful if you have large scripts, as quake3 has a limit to the number of shaders that can be displayed at a given time.  So, you can turn on the most useful items to you - most likely IDs, CAMs, and ACTPOINTs.
