The "moreChars" test in StaticLayout's generate method would evaluate to
false when the last character in a word caused the break. This in turn
suppressed the ellipsis in this case. The proposed fix is always to set
moreChars true in the code path where the line is broken because more
text wouldn't fit.

libcore now offers a wider variety of 12-/24-hour time formats,
so be more specific about which one we want here.

The motivation is an API change: FloatMath is going to be
deprecated and/or removed. Performance is not the goal of
this change.
That said...
Math is faster than FloatMath with AOT compilation.
While making the change, occurances of:
{Float}Math.sqrt(x * x + y * y) and
{Float}Math.sqrt({Float}Math.pow(x, 2) + {Float}Math.pow(y, 2))
have been replaced with:
{(float)} Math.hypot(x, y)
Right now there is no runtime intrinsic for hypot so is not faster
in all cases for AOT compilation:
Math.sqrt(x * x + y * y) is faster than Math.hypot(x, y) with
AOT, but all other combinations of FloatMath, use of pow() etc.
are slower than hypot().
hypot() has the advantage of being self documenting and
could be optimized in future. None of the behavior differences
around NaN and rounding appear to be important for the cases
looked at: they all assume results and arguments are in range
and usually the results are cast to float.

All supported locales use only U+2025 and U+2026 to represent
ellipses, and it will unlikely change in future. Given translated
resources are inconsistent and often use three dots it is safer
to use constants instead of resources.

With a hardware keyboard, using up arrow within the top line should
move to the beginning of the buffer, to better match desktop text
editing expectations, and similarly for down arrow on the last line.
This patch implements that behavior.

We weren't getting correct results from Layout.isRtlCharAt, because it
was only testing half of the correct predicate for whether the argument
was inside the run. This patch restores the correct predicate.

The test fixes for bug 17262063 showed up a real issue for
non-English locales with the Time.format() method:
If the Android string resources that contain the pattern use
non-ASCII characters then a '?' would be output instead of
those characters.
For example, in France the pattern for '%c' includes a 'à'
(a with a grave accent) and Japan includes 日.
The problem was due to converting the pattern to bytes using
the US_ASCII character set, which turns non-ASCII characters
into '?'. The code has been changed to use char throughout
and avoid bytes.
Internal documentation has been improved.
Some calls to modifyAndAppend() have been replaced with a
direct call to outputBuilder.append() because the
modify step is guaranteed to a no-op for the literals given.
The formatter has been changed to use Locale.US because it
is only used for outputting numbers. It has been renamed
to make this more obvious and the locale field has been
removed.

We used the full width of a line, including trailing spaces, to compute
ellipsis, sometimes causing spurious ellipsization when the space pushed
it past the layout width. This patch uses only the width up to the last
graphing character.

This addresses b/16486549.
This change updates public documentation to specify the behavior of
LeadingMarginSpan2s. This change specifies what happens when a
LeadingMarginSpan2 is combined with other LeadingMarginSpans. This
behavior was not previously documented.
LeadingMarginSpan2s specify the number of lines used for the leading
margin. When laying out and rendering, for all LeadingMarginSpans, the
first line margin is applied for the number of lines specified by the
LeadingMarginSpan2.
Previously, this behavior was slightly buggy -- the LeadingMarginSpan2
affected all LeadingMarginSpans when laying out text, but not when
rendering.
This change is designed to cause the least amount of breakage in
existing code while achieving consistency with the way
LeadingMarginSpan2 is handled in layout and drawing.
For the most common use of LeadingMarginSpan2 -- getting a multi-line
first margin in the first paragraph of text in a layout -- this should
cause no change in behavior. For any other uses, the old (buggy)
implementation most likely did not exhibit correct behavior to begin
with, so developers were most likely not relying on that functionality.

This fixes b/16510772.
When measuring paragraphs, leading margins should be taken into account.
When computing line width, the margin should be added to the absolute
value of the extent (there were missing parenthesis). Both of these
caused views with leading margins to be rendered incorrectly.

The reason for separate classes for each type, instead of a more flat
structure is to enable easy discovery of the available arguments that
can be set. For L we'll have about 12 types with 30 arguments and
almost all of the arguments are type specific. In future releases
we'll introduce more arguments. With editors that have code completion
one can construct a span without having to consult the documentation.
For now it only contains Text and Cardinal types.
