Masayuki suggests GetCharcterRectsInRange instead of first idea's API by part 2 implementation.
IME wants to need the width per character. Now nsTextFrame/nsIFrmae has only API to get point of string. So I want to add this method to calculate simply by comment #3.
If no text frame, I would like to return error due to no character. (Caller shouldn't call this API on non-text frame.)

This patch defines mozilla::SelectionType as an enum class. This is safer than nsISelectionController::SELECTION_* since setting illegal value to its variable is checked at build time. So, as far as possible, this should be used everywhere (but of course, this isn't available in scriptable interfaces).
And also this implements some useful methods for managing SelectionType and RawSelectionType which are implemented in layout/nsSelection.cpp because nsISelectionController is implemented by both PresShell and nsTextEditorState. Therefore, implementing one of them may make hard to find them. On the other hand, nsSelection.cpp is a better file name to look for them.
Note that this patch creates mozilla::Selection::RawType() for binding. Native code should keep using Selection::Type() but the binding code needs to use RawType() due to impossible to convert from SelectionType to RawSelectionType without explicit cast.

mozilla::SelectionType will be an enum class. Therefore, we need to rename SelectionType with a word "raw" since it's a type for raw nsISelectionController::SELECTION_*.

Bug 655877 Part 20 made this deliberately to let nsTextFrame
QueryFrame-able. https://hg.mozilla.org/mozilla-central/rev/d8c6025c0881
But other types like nsPlaceholderFrame or nsBulletFrame are also
implemented QureyFrame, which do not have this inheritance indirection.
I guess it was for historical reason, and can be removed safely.

Although this makes some places more complicated, code should generally
be simpler and clearer. It could slightly improve performance on x64 for
functions with more than four parameters, since it makes more data be
passed via registers rather than the stack.

AutoTextRun now only needs a DrawTarget instead of an nsRenderingContext, and
similar nsRenderingContext/gfxContext-to-DrawTarget replacements can be
propagated a long way up the call graph. This patch replaces 93 occurrences of
nsRenderingContext and 135 occurrences of gfxContext with DrawTarget; that's
13% of them.
The patch is mostly plumbing changes. A couple of not-entirely-plumbing
changes:
- It adds a comment about the null check in
gfxGlyphExtents::GetTightGlyphExtentsAppUnits().
- A couple of functions simply had an unused gfxContext or nsRenderingContext
parameter removed, e.g. SetLineBreaks().
