void RtCoverageRegion::SplitHorizontally	(	RtCoverageRegion &	lowpart,
		RtDWORD	hisize
	)

Splits the region by dividing it to upper and lower part. Upper part is stored in this instance, lower part is filled into lowpart parameter

Parameters:

	lowpart	returned lower part of former region
	hisize	height of higher part

void RtCoverageRegion::SplitVertically	(	RtCoverageRegion &	rightpart,
		RtDWORD	leftwidth
	)

Splits the region by dividing it to left and right part. Left part is stored in this instance, right part is filled into rightart parameter

Parameters:

	rightpart	returned right part of former region
	leftwidth	desired witdth of left part
