2.15.0.1067 - transparency not supported in sleepscreen

[Andrea Panontin]

I updated to 2.15.0.1067 and if I replace the suspended.png file with a custom one with transparency, the transparent parts of the file get rendered white, masking the content beneath. (Of course I applied your patches before doing this.)

I have the same issue on 2.15.0.1067-patch_38.2.01-0-gdbdbd93.
