absense of the window is represented by "close".
The feature minimization stands for is called "iconification", and it's not
far fetched to associate that with e.g. the icons in the Unity launcher.
otoh, minimization can be any form of semantic scaling of a content item,
e.g. preview, thumb etc..
so in that respect, i find it reasonable to indicate a direction of
movement, rather than using an abstract symbol such as "-" or a dot.
