Okay, I see how I can use GetClloffCount to record the stack depth and then trim it to the same level when I'm done, but I'm not sure why all this stack manipulation should be necessary for something so simple. What I realy want is something like the ModelView matrix stack in in OpenGL.

The following methods would do exactly what I want:
Win32:

void Draw::AddOffsetOp(Point p)
{
	DrawLock __;
	actual_offset += p;
	LTIMING("Offset");
	SetOrg();
}

X11 (not tested):

void Draw::AddOffsetOp(Point p)
{
	Cloff &f = cloff.Top();
	actual_offset += p;
	offset[f.offseti] = actual_offset;
}

Or does this break something else (Drawing)?
