---------------BUGS-------------------
--* 1)		There's a period in between entering and exiting a vehicle whereby the camera switches its "lock on" from the ped to the vehicle or vice versa
--		During this period, It is not possible to rotate the camera, but getCameraMatrix returns the lookAt point as if it had rotated.  
--		This means the customblip rotates like crazy but the radar doesnt
--
--* 2)		showPlayerHUDComponent has the ability to hide the radar, but custom blips is not aware of this.
--		All scripts would also need to hook into customblips to notify it whenever hiding the radar
--
-- Bug #2 is most easily fixed if we get a isRadarVisible/isPlayerHUDComponentVisible function or something to that effect
