DESCRIPTION:
Gets a list of light sources associated with the active part or assembly.

This function allocates memory for the list of light sources.
This memory MUST be deallocated by the calling procedure.

Example:

   int i;
   int Count=0;
   svxLight *Lights=NULL;

   cvxLightGetAll(&Count, &Lights);
   for (i=0; i < Count; i++) {Light[i]...}
   cvxMemFree((void**)&Lights);

Return 1 if error, else 0.

void cvxDispRedraw (void)
/*
DESCRIPTION:
Initiates a screen redraw if display update is not disabled 
and if a redraw is not going to be forced at the end of the
current operation.  

Active inputs (i.e. picks and previews) are not redrawn.  If 
you desire a redraw that includes redisplay of active inputs,
use cvxCmdSend("$CdRedrawAll").

void cvxDispSwitch
(

)
/*
DESCRIPTION:
Switches OFF automatic display update of the specified GUI item
when "isOn=0".  Switches it back ON when "isOn=1".

Each call to this function with "isOn=0" MUST be paired with 
a subsequent call to this same function with the same "Item" 
setting and "isOn=1" in order to restore the setting to 
its original state.  This is CRITICAL for the VX display to 
function properly after your application is done.

By default, display update is ON, so this function should ALWAYS
be called first with "isOn=0" followed by a call with "isOn=1".

Returns 1 if function fails; 0 if it succeeds.
