- Inline -> Pargraph. This class is actually a box, not an inline. It's really
a wrapper for RenderParagraph, so Paragraph is the normal name.
- InlineBase -> RenderInline. The name we used in C++ for the base class of
all inlines was RenderInline, which removes the ugly "Base" suffix.
- InlineText -> RenderText. Aligns this name with C++.
- InlineStyle -> RenderStyled. Matches the foregoing pattern.
