Bug: 15594400
Change-Id: Ied94d7674be4097b0f44c9b0770d3294dc6433c1

Change internal plumbing of paint flags (including CssParse) to uint32_t
consistently, to match the type used in the client. This will probably
prevent compiler warnings. Also renames "float" to "double" to avoid
confusion about precision.

Adds pseudo-css properties for scaleX and skewX, as well as paint flags,
and plumb them through to the MinikinPaint abstraction and to Harfbuzz,
to support nontrivial scale and stretch of text.

This is the Minikin part of the fix for bug 15186705 "Usability of the
suggestion strip in recent OTA's is severely reduced"

This patch adds a "lang" pseudo-CSS property and uses it both to select
an appropriate font and control the "locl" OpenType feature to get the
most appropriate rendering for the langauge and script.  In addition,
the "-minikin-variant" property selects between "compact" and "elegant"
variants of a font, as the former is needed for vertically cramped
spaces.

This is part of the fix for bug 15179652 "Japanese font isn't shown on
LMP".

This patch contains a very basic implementation of BiDi. It respects the
BiDi flags passed in as an explicit parameter (through the
"-minikin-bidi" pseudo-CSS property), but doesn't yet do its own BiDi
run detection. It also takes some shortcuts (marked as TODO) that are
based on reasonable assumptions of the current font stack, but not
universally valid.

Even with these shortcomings, it seems to display RTL text from TextView
correctly.

This is the initial draft of Minikin, a library intended to perform text
layout functions. This version does basic weight selection and font runs
for scripts, and also has a simple renderer for drawing into bitmaps,
but is lacking measurement, line breaking, and a number of other
important features. It also lacks caching and other performance
refinements.
