schematics. Cschem merely permits having such styles not by defining
and hardwiring each of them in code, but by separating the looks from the works.

text object and font
+{imp3:20} There are two ways to specify font geometry of a text object:
+
+ - {imp3:21} bbox based: when x2;y2 are specified; this is useful for
+ fixed text objects placed on the sheet by the user; it's more important
+ that these text objects, especially when multiline, stay in place and
+ don't start to overlap with other objects than to have the exact font
+ size matched.
+
- {imp3:22} pen height based: when the text object does not have
+ x2;y2, pen height property is used; this is useful when the
+ placement and approximate size of the text is important but
+ bbox matching is not. This is the typical case in symbols.

grouping
{imp3:10} Cschem has only one kind of group and allows group-in-group.
