%DIPCLF   Clears figure windows created by DIPSHOW
%   DIPCLF clears all figure windows created by DIPSHOW, without
%   changing their position or size.
%
%   DIPCLF(H) clears the figure window with handle H. If H is zero,
%   clears all figure windows. H can be a numeric array [H1,H2,H3]
%   or a cell array {H1,H2,'varname1','varname2'} or just a variable
%   name. The window associated with that name is cleared.
