Better window placement and auto resizing to better display the DAG

[pmiossec]

• ONLY after loading a new repository
• on the top left of the WorkArea (to be able to have a git window on the right)
• never bigger than the WorkArea
• Add a button to let the user resize when he wants

Hi Phillipe,

This looks much better :-) The usability is much better now. Thanks!

Unfortunately I ran into a problem when when using multiple monitors. The ResizeWindowDependingOnGraphSize() method will crash when trying to calculate the new width because Left is > PrimaryScreenWidth. This happens when I have a second monitor positioned to the right of my primary. Also, PrimaryScreenWidth only returns the width of the primary display, not the width of a secondary display, which may be where GitViz is running.

You might want to look at http://stackoverflow.com/questions/254197/how-can-i-get-the-active-screen-dimensions/254241#254241 to see how to get the width of the current screen. You might also want to look at http://geekswithblogs.net/JeffFerguson/archive/2010/06/14/calculating-screen-resolutions-using-wpf.aspx given the increase on high DPI displays going around these days :-)

I have fixed the crash about the multiscreen support. Thanks for the links it was very helpful!

For the High DPI support, I think I can't do something :(
I have written the beginning of something (based on the link you gave me) but, because I don't have a high DPI screen, PresentationSource.FromVisual(Application.Current.MainWindow) is always null and I can't do nothing :(

If someone need it, he will have to do it himself... I can create a pull request with what I did but It is difficult for me to imagine what values of width, height, left and top will be returned and where the factor should be applied :(

Agreed re high DPI screens. We might wait until the WPF team deliver on their roadmap :-)
