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can be removed in the future when the Font Manager can be superceded.

SkPaint::measureText and text drawing used different criteria for
determining whether text should be drawn as paths or not.
Adds tests glyph_pos_(h/n)_(s/f/b) to test the text rendering and the glyph
positioning in the rendering. Mainly added in order to define what is the
expected text rendering when hairline stroke is used with various transform
options.
The testcase also tries to note or highlight the fact that SkPaint::measureText
is not expected to produce intuitively matching results when compared to a
rendering, if the rendering is done so that the device ends up having a device
transform.
This fixes the glyph_pos_h_s (hairline, stroked) test-case.
Ignore shadertext2_pdf-poppler.png gm on
Test-Ubuntu13.10-ShuttleA-NoGPU-x86_64-Debug temporarily, as that fails.
