Summary: Alpha channel is incorrectly converted to mask
When loading a PNG image with an alpha channel to a
wxBitmap, the alpha information can sometimes be lost
if the wxImage loader converts the alpha channel to a mask.
Workaround is loading it in two steps, setting the
wxImage back to having an alpha channel before passing
it to the wxBitmap constructor.
wxBitmap bmp("image.png", wxBITMAP_TYPE_PNG); //
sometimes loses alpha channel
