Merge lp:~frank-niessink/squaremap/fix-for-taskcoach into lp:squaremap

[Frank Niessink]

Hi Mike,

Without this one line patch I get errors in Task Coach. It seems the Squaremap code currently assumes that OnSize is always called at least once before OnPaint. If not, an AttributeError happens when trying to access the _buffer. I think it is safer to create a default _buffer in __init__ so this cannot happen at all.

Cheers, Frank

PS: This is not new, previous versions of Squaremap also had this issue. Until now I had only made the change in our copy of Squaremap without sending you the patch. If you accept this patch, we will have a pristine copy of Squaremap in our repository, yay.
