aquabutton - exception on resize

If resizing a panel containing aquabutton I get this exception when size is getting small.

root - ERROR - app_base.py - 343 - Traceback (most recent call last):
   File "c:\python27\lib\site-packages\wx-2.9.2-msw\wx\lib\agw\aquabutton.py", line 348, in OnPaint
     self._storedBitmap = wx.EmptyBitmapRGBA(width, height)
   File "c:\python27\lib\site-packages\wx-2.9.2-msw\wx\_gdi.py", line 1009, in EmptyBitmapRGBA
     return _gdi_._EmptyBitmapRGBA(width, height, red, green, blue, alpha)
ValueError: Width and height must be greater than zero

A work around is to change line 348 from:

             self._storedBitmap = wx.EmptyBitmapRGBA(width, height)

to:

             self._storedBitmap = wx.EmptyBitmapRGBA(width+1, height+1)

A bit of a hack, one should probably check for zero and only then add 1.

I usually do something like (max(width,1), max(height,1))

A work around is to change line 348 from:

       self\.\_storedBitmap = wx\.EmptyBitmapRGBA\(width, height\)

to:

       self\.\_storedBitmap = wx\.EmptyBitmapRGBA\(width\+1, height\+1\)

Thank you for the bug report, it should be fixed now in SVN.
