space table better for Constants
should Return be on same line as 'Return Value'?
remove anonymous header, e.g. Enum SkPaint::::anonymous_2
Text Encoding anchors in paragraph are echoed instead of being linked to anchor names
also should not point to 'undocumented' since they are resolvable links
#Member lost all formatting
#List needs '# content ##', formatting
consts like enum members need fully qualfied refs to make a valid link
enum comments should be disallowed unless after #Enum and before first #Const
... or, should look for enum comments in other places
trouble with aliases, plurals
need to keep first letter of includeWriter @param / @return lowercase
Quad -> quad, Quads -> quads
check for summary containing all methods
