I found 2 issues when hosting linux vst plugin windows using juce code:
- some guis will have their bottom cut off

- when not using native titlebar the window is still resizable via WM
see http://i.imgur.com/MKFRD6G.png, note the "resize" option is not greyed out.
Fixed those just now, patch here:
