Update by [Minecraft] Mega_Spud (Jay Wells):
Transparent parts of player skin are not showing properly, and just show as black.
Steps to Reproduce:
Notice the transparent parts just render as opaque black
If the total skin transparency does not exceed the maximum allowable amount, then those parts should be invisible.
Screenshots/Videos attached: Yes
Skin transparency appears to be completely broken- as any transparent pixel at all renders as black in-game. The images show the same skin used in 1.1.5 and 1.2
