* In 2011 gEDA/pcb introduced values with units, like "10mm" or "200mil".
* Unit-less values are still centimils (100000 units per inch), like with
* the previous format.
*
* Distinction between the even older format (mils, 1000 units per inch)
* and the pre-2011 format is done in ::parseFOOTPRINT already; the
* distinction is by whether an object definition opens with '(' or '['.
* All values with explicit unit open with a '[' so there's no need to
* consider this distinction when parsing them.
*
* The solution here is to watch for a unit and, if present, convert the
* value to centimils. All unit-less values are read unaltered. This way
* the code below can continue to consider all read values to be in mils or
* centimils. It also matches the strategy gEDA/pcb uses for backwards
* compatibility with its own layouts.
*
* Fortunately gEDA/pcb allows only units 'mil' and 'mm' in files, see
* definition of ALLOW_READABLE in gEDA/pcb's pcb_printf.h. So we don't
* have to test for all 11 units gEDA/pcb allows in user dialogs.
