You shouldn't have to manually set the texture coordinates like that if
you don't want; you could use ->setImage("...", true) with the right Y
setting in the WindowManager and it should behave how you want. Either
way is fine, though. :)

I don't think there's a bug. Try calling:
left->setColor(1.0f, 1.0f, 1.0f, 1.0f);
...and it should be just fine. Be default, a Label object sets it's
Widget color to be completely transparent, so I'm guessing the texture
is there just not visible (or rather, it's alpha is 0.0f).
