libpng warning: "iCCP: Not recognizing known sRGB profile that has been edited"

[ARNdroid]

As we updated project to API 21 (Android 5.0) by #84, we have received warnings at gradle (clean) compile/build time like:

We starred an open issue about it in AOP.

Some research here:

• http://tex.stackexchange.com/questions/125612/warning-pdflatex-libpng-warning-iccp-known-incorrect-srgb-profile
• http://stackoverflow.com/questions/22745076/libpng-warning-iccp-known-incorrect-srgb-profile

We need to think about getting rid of these warnings.

After migration to AS 1.2.0 (#205) the warnings concern only project files (no more warnings for Android Support Library are shown):

It's time solve it!
