Backport changes/fixes related to tile-based decoder from Honeycomb to
Gingerbread.

Bug: 3309014

////////////////////////////////////////////////////////////////////
This is a combination of 3 commits.

Fix 3071104, where decodeRegion returned false for some large image.

decodeRegion() returns false when it cannot find a suitable color config
for SkScaledBitmapSampler. Currently SkScaledBitmapSampler does not
support RGB_565. If cinfo->out_color_space is set to RGB_565 and we
require SkScaledBitmapSampler to do the extra sampling, we will fail in
finding a suitable color config for SkScaledBitmapSampler.

To fix it, we add support of RGB_565 into SkSclaedBitmapSampler.

Fix 3117581, where BitmapRegionDecoder fails in building tile index for
PNG files.

The virtual method of building tile index in SkImageDecoder was changed to onBuildTileIndex().
SkPNGImageDecoder needs to override the method.

Add fPreferQualityOverSpeed to SkImageDecoder.

Currently the field only affects JPEG decode, in that when it is set
to true, we choose a more accurate, but slightly slower, IDCT method.

The calculation of actualSampleSize should be rounding up not down.

Merge commit '4701b5d2' into kraken

* commit '4701b5d2':
  Corrected a bug in SkPaint::breakText.
  Added GetUnitsPerEM method to SkFontHost

Change-Id: Ic7024b390883841714ac6fb5f6a11f87a9f707a6

The bug occurs when linear text is meassured. E.g. without this
correction, the following test case will fail

  String s = new String("abcdef");
  Paint p = new Paint();
  p.setLinearText(true);
  float width = p.measureText(s);
  int numberOfCharacters = p.breakText(s, true, width, null);
  assertTrue(numberOfCharacters == s.length());

The reason for this bug is that canonical text size is used to messure
linear text while the maxWidth is not scaled correspondingly.

GetUnitsPerEM can be used as convenience method to
find out the number of font units per EM square
without having to fetch the head table.

Bug: 2638848
Change-Id: I4e028825bfb45b2a4c484899f3ec4cba3d96deb1

Without this this patch, an application could trigger a platform crash
by calling:

  Typeface typeface = Typeface.createFromFile("");
  boolean isBold = typeface.isBold();

The crash occurs since the find_name_and_style function does not
return an error code.

The drawPosTextOnPath method allows for text positioned on
a straight line to be drawn along a path.
This method can be used by layout engines to implement the
Canvas::drawTextOnPath method for complex scripts.
