Replace manually entered summary tables with ones that are populated and sorted by bookmaker. This introduces a slight regression for anonymous enums but fixes a lot of bugs and omissions. The format is #Topic somethingTopical #Populate ## where somethingTopical is one of Subtopics, Constructors, Constants, Classes_and_Structs, Members, Member_Functions, and Related_Functions. Fix the bad formatting in SkCanvas reference. The #Error tag was was corrupting the markdown table. Remove the tag and replace it with #NoExample. Next up: revise self-check to know about populated topics.
