Incorrect values when units are not in lowercase

[moretti]

For example calc(50% - 42Px) is translated to calc(0.5 - 42Px)

(We declare some units in capital case in conjunction with postcss-pxtorem)

Is this valid per css specs ?

[moretti]

Yes, it is. From http://www.w3.org/TR/CSS21/syndata.html:

All CSS syntax is case-insensitive within the ASCII range (i.e., [a-z] and [A-Z] are equivalent), except for parts that are not under the control of CSS. For example, the case-sensitivity of values of the HTML attributes "id" and "class", of font names, and of URIs lies outside the scope of this specification. Note in particular that element names are case-insensitive in HTML, but case-sensitive in XML.

So PR is welcome =)
