Subject: Add a pre/post draw call back to strobe lights so we can make them bigger
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=9c561ab860f0799c2ebb3d588ec8dfbfbcc991b8;p=flightgear.git

Add a pre/post draw call back to strobe lights so we can make them bigger
so they will stand out from everything else.
