[iip] Differences in physical size for fonts affects baseline alignment (#96)

r12a has just created a new issue for https://github.com/w3c/iip:

== Differences in physical size for fonts affects baseline alignment ==
By and large, Indian scripts in browsers are rendered with default fonts provided by back-end Operating Systems. If there are major differences in physical size for a particular font size, which most of the times are, it shows the mixed-script text in an un-organized way. This obviously affects all the base-line attributes.

Generally, Indian scripts that have joining line use the joining line as the baseline. Ideally, if a document contains both Devanagari and Gurmukhi text (such as <em>Mahan Khosh</em>), the text should be aligned at the joining line regardless of the script or font.
