Addresses a regression in Calendar where a custom drawable that doesn't
implement intrinsic bounds is laid out incorrectly. Also fixes an issue
where ColorDrawable would be laid out incorrectly.

For correct low-level drawing of low level text, a method that
includes context for shaping is necessary, and it's similarly useful
to provide the direction explicitly rather than running the BiDi
algorithm on the text. The drawTextRun method (in both char[] and
CharSequence variants) has provided this functionality for several
major releases but has been internal. This patch exposes the
methods publicly, and also improves the doc strings for both
the new method and some related ones.

Failing to check the return result from intersect() can cause artifacts
because the developer may assume that the rect has been changed to the intersection.
In particular, when the two rects do not overlap, there is no change made to the
source rect. Instead, the method simply returns false. When developers do not
check that return value, they may use the source rect and get undefined results.
This change adds the @CheckResults annotation that will cause a Lint warning
when developers call this method without checking the return value.

Adds explicit padding attributes to LayerDrawable, constrains the ripple
to fit within the container to avoid projection.

Adds methods to Paint for finding an offset corresponding to an
advance, and for finding the advance corresponding to an offset,
useful for positioning and drawing a cursor.

Switch a few places to using android::canvas
instead of SkCanvas as well which eliminated
some JNI

Stop assuming that a Java Bitmap has a SkBitmap* that
has some externally managed lifecycle, and instead switch
a bunch of users to accessing the bitmap by providing
their own SkBitmap* on which to set the (ref counted!)
SkPixelRef* instead

This patch adds a method to determine whether a typeface has a glyph
to support a particular Unicode character or sequence.
The implementation is based on shaping the text and checking for the
presence of .notdef glyphs, and counting the number of glyphs in the
ligature case. In the case of variation selector control characters, it
currently just returns false because there is no variation selector
support yet (Mongolian Free Variation Selectors work because they're
shaped with GSUB instead).

Originally, stroke width is independent of group scaling.
But that is a bug and causing animation trouble.

The cursor position calculation of not well known CharSequence implementation
has problem. getTextRunCursor() returns the relative path of passed string
buffer, so need to fix the origin by adding the copied buffer origin.

Issue #17140095 Drawable#getOpacity() is documented as ignoring custom alpha, e.g. setAlpha(). It is lying.
