2018-07-30Don't static_cast<>(this) to subclass in CXFA_LayoutItem methods.chromium/3508Tom Sepez
Instead, move the methods to the subclass where they belong. Fix IWYU in CJX_Object.h to fix compilation.

2018-07-30Type-safe iteration over CXFA_ContentLayoutItems.Tom Sepez
There's no reason that every CXFA_LayoutItem must be a CXFA_ContentLayout item, so use checked conversions. The code may already be arranging things so the constraint is already satisfied, but this adds an additional layer of safety. Tidy some long expressions with pre-existing typedef for node iterator while we're at it.
