Convert 'proportional-column-width' datatype to compound datatype
It would be simpler if the 'proportional-column-width' datatype was
a compound datatype with 'length' and 'proportional' components.
This would reduce the calculations done when a table has no columns
with proportional width.
Convert fo-expr-context-private.h _get_ functions to macros
Macros were turned into functions when the header file was going to
be publicly visible, but since it is now private to the expression
parsing code, the functions could easily be made into macros again.
Merge all enumeration tokens into one large GEnum
Since, in principle, a property can get its value from almost any
other property type by using inherited-property-value(),
from-parent(), from-nearest-specified-value(), or
from-table-column(), maybe all enumeration tokens should be in one
large GEnum, with a property required to check that a particular
value from another property is valid for the current property.
Maybe this doesn't fit with the current practise of turning
enumeration tokens into resolved values straight away.
Remove 'context' parameter from _resolve_enum() functions
The FoContext is unnecessary once none of the _resolve_enum()
functions handle the 'inherit' keyword.
This will also affect _validate() functions of properties, since
they will also no longer need a 'context' parameter.
Convert property value calculations to use functions in fo-datatype.h
Calculations involving property datatype's values can be simplified
by using the functions in fo-datatype.h.
Update remaining formatting objects and properties to match current
spec-dump
This is a never-ending process while the spec-dump stylesheets are
being continually tweaked.
