app/window,app/internal/window: allow min/max window size

Browse Source 
The app.MinSize and app.MaxSize options restricts the window size:

w := app.NewWindow(
	app.Size(unit.Dp(600), unit.Dp(596)),
	app.MinSize(unit.Dp(600), unit.Dp(596)),
	app.MaxSize(unit.Dp(600), unit.Dp(596)),
	app.Title(APPNAME),
)
