QisLib_SetStructureDisplayFilterSize

QisLib_SetStructureDisplayFilterSize

Function:
	int QisLib_SetStructureDisplayFilterSize(int SizeInPixel);

Inputs:
	SizeInPix: Cell references smaller than SizeInPixel pixels are not processed.

Return: 0

Errors: -

Description:
	- All cells references with size in the current view less than the display filter size
	in pixels will not be drawn or processed.
	- This is to avoid loss of time processing cell references that are so small in the
	current view that they dont provide any useful information to the user.
	- SizeInPix must be greater than or equal to 0. If SizeInPixel is 0, all cell
	references will be processed or drawn.
	- As we zoom in, the display size of the cell references increases and thus will
	become visible when they become bigger than the specified display filter size.
	- This command does not affect QisLib_GetDataVector but does affect
	QisLib_GetDisplayVector.
	- The QisLib_DisplayFilterSize takes precedence over
	QisLib_SetStructureDisplayFilterSize and hence cells references smaller than
	QisLib_SetDisplayFilterSize are also not drawn.
	- The default size is 20 pixels.
	- Functions such as QisLib_SetSDFFill, QisLib_SetSDFColor etc. can be used to control
	how filtered cell references are drawn.
