/* todos:
add new markup to associate enum SaveLayerFlagsSet with typedef SaveLayerFlags, if needed.
should Return be on same line as 'Return Value'?
#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
deprecated methods should be sorted down in md out, and show include "Deprecated." text body.
rewrap text to fit in some number of columns
#Literal is inflexible, making the entire #Code block link-less (see $Literal in SkImageInfo)
would rather keep links for boby above #Literal, and/or make it a block and not a one-liner
add check to require #Const to contain #Code block if defining const or constexpr (enum consts have
#Code blocks inside the #Enum def
add spelling rule to look for x-bit but allow x bits
There are a number of formatting bugs with ad hoc patches where a substitution doesn't keep
the space before or after, or the linefeeds before or after. The rules are not very good either.
Linefeeds in the bmh file are intended to be respected, but #Formula tends to start on a new line
even if the contents is intended to be inlined. Probably need to require it to be, e.g.:
array length must be #Formula # (fXCount + 1) * (fYCount + 1) ##.
where there is always a space between prior words and formula (i.e., between "be" and "(fXCount";
and, an absense of a space after ## denotes no space between "+ 1)" and ".". These rules preserve
that # commands are always preceded by a whitespace character. Similarly, #PhraseDef/Ref
need to be inline or create new paragraphs. #phrase_ref# is sufficiently flexible that it can be
treated as a word without trailing whitespace, adapting the whitespace of its context. It also must
always have leading whitespace.
It's awkward that phrase param is a child of the phrase def. Since phrase refs may also be children,
there is special case code to skip phrase def when looking for additional substitutions in the
phrase def. Could put it in the token list instead I guess, or make a definition subclass used
by phrase def with an additional slot...
#Deprecated soon
##
should emit the text "To be deprecated soon." (right now you get just "soon")
SkCanvas_ColorBehavior_kLegacy missing </table> in md out
rearrange const out for md so that const / value / short description comes first in a table,
followed by more elaborate descriptions, examples, seealso. In md.cpp, look to see if #Subtopic
has #Const children. If so, generate a summary table first.
Or, only allow #Line and moderate text description in #Const. Put more verbose text, example,
seealso, in subsequent #SubTopic. Alpha_Type does this and it looks good.
more spelling: x-value y-value
see head of selfCheck.cpp for additional todos
