Add a couple of utility functions to SkPaint that return the bounds
of glyphs between a pair of lines.
The common use case envisioned generates the edges of descenders
between the top and bottom bounds of an underline to allow computing
a stroke that skips those descenders.
The implementation stores a linked list in each glyph containing
the bounds of the lines parallel to the advance and the outermost
intersections within those bounds.
When the glyph cache is constructed, the glyph path is intersected
with the bounds and the extreme min and max values within the bounds
is added to an intercept.
Share the text to path iter to construct the data.
Make a half-hearted attempt to support vertical text; while the
vertical implementation is complete; surrounding code (e.g. paint
align) has short-comings with vertical.

I have verified locally that nothing draws differently.
Motivation:
* SK_SIMPLE_GM makes it easier to write a GM.
* Reducing 1100 lines of code makes maintenance easier.
* Simple GMs are easy to convert to Fiddles.

This fixes every case where virtual and SK_OVERRIDE were on the same line,
which should be the bulk of cases. We'll have to manually clean up the rest
over time unless I level up in regexes.
for f in (find . -type f); perl -p -i -e 's/virtual (.*)SK_OVERRIDE/\1SK_OVERRIDE/g' $f; end

Allow GM results to be compared across machines and platforms by
standardizing the fonts used by all tests.
This adds runtime flags to DM to use either the system font context (the
default), the fonts in the resources directory ( --resourceFonts ) or a set
of canonical paths generated from the fonts ( --portableFonts ).
This CL should leave the current DM results unchanged by default.
If the portable font data or resource font is missing when DM is run, it
falls back to using the system font context.
The create_test_font tool generates the paths and metrics read by DM
with the --portableFonts flag set, and generates the font substitution
tables read by DM with the --resourceFonts flag set.
If DM is run in SkDebug mode with the --reportUsedChars flag set, it
generates the corresponding data compiled into the create_test_font tool.
All GM tests set their typeface information by calling either
sk_tool_utils::set_portable_typeface or
sk_tool_utils::portable_typeface .
(The former takes the paint, the latter returns a SkTypeface.) These calls
can be removed in the future when the Font Manager can be superceded.

Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer
a step each in the hierarchy.
What used to be this:
SkFlattenableWriteBuffer -> SkOrderedWriteBuffer
SkFlattenableReadBuffer -> SkOrderedReadBuffer
SkFlattenableReadBuffer -> SkValidatingReadBuffer
is now
SkWriteBuffer
SkReadBuffer -> SkValidatingReadBuffer
Benefits:
- code is simpler, names are less wordy
- the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed
- write buffers are completely devirtualized, important for record speed
This refactoring was mostly mechanical. You aren't going to find anything
interesting in files with less than 10 lines changed.

Move Line2DPathEffect (now Sk_) into a separate header file so it can
be shared and initialized.
Switch to the shared version in SampleAll and SampleSlides.
Remove the skip pipe flag from texteffects, since it can now be serialized.
I have a separate change to turn serialization on by default at https://codereview.appspot.com/6498121/
