Known issue: "tint black" checkbox

[NikolayJuly]

I notce difference in rendering of some pixels of alien skeletons. After searching, I found that spine has check-box "tint black", which actually tint only black pixels to tint color. This is not supported, and will be problematic to support, because we render whole skeleton with one draw call. Which means one shader, which not supporting this "tint black" only checkbox.

This is how it shoud looks like when "tint black" is supported	This is how package rendering color - just take color form texture
