libui/checklist_attrstr

= attributed strings
attribute lengths are rounded to complete unicode codepoints
zero-length attributes are elided
consecutive attributes of the same type and value are merged
overlapping attributes of different types do not split each other
overlapping attributes of the same type but different values do split
empty string is allowed
empty string cannot have attributes
font family names are case-insensitive both in attributes and in descriptors
Okay, I need to rethink these APIs. Let's start doing so. Then I should also write a testsuite for uiAttributedString. 2017-11-05 21:52:14 -06:00			`= attributed strings`

More attributed string API work. Of note, decided to make each type of attribute have its own field in uiAttributeSpec, to make thinking about what to do next easier (and because why not). 2017-11-06 22:58:12 -06:00			`font family names are case-insensitive both in attributes and in descriptors`
