Function CreateSmallView

Descent3/SmallViews.cpp:207–250

Create a new small view. If there is already a view in the given window, the old view gets blown away. Parameters: window - which window to open. See constants in SmallViews.h objhandle - handle for the object to view from flags - various view attributes. See defines in header file. time - how long to keep the window up. If 0, keep up indefinitely zoom - the zoom for this window. If 0, use th

//					label - the label for the window
