Fixes regarding densities in "Providing Resources" documentation page.
The ratio between densities is not constant.
The Exception for dpi qualifier in point 4 of the algorithm should be detailed.

and I have the choice between mdpi and hdpi-trackball-v5, mdpi will be chosen.
Cherry-picked from master CL 59188.
