Ionic resources doc issue

ionic help resources says

       		      Splashscreens should be 2208x2208 px, with the image centered in the midd

but if you serve it a 2208x2208 png file, it complains

splash ios Default-Portrait@~ipadpro.png (2048x2732) skipped, source image splash.png (2208x2208) too small

I think this is a documentation issue. Apparently ipadpro needs bigger image source.

cli version : v2.0.0-beta.36
