scroggo@google.com 74b7ffda68 Fixes for piping bitmaps with encoded data.
Similar goals as https://codereview.chromium.org/14437012.

Builds on patch set 1 from that issue
(https://codereview.chromium.org/14437012/#ps1).

Instead of the changes in patch set 2 from that issue, this
changes SkOrderedWriteBuffer::writeBitmap to store whether an
SkBitmapHeap was used when to store the index of the SkBitmap.
SkOrderedReadBuffer::readBitmap now uses that information to
distinguish between using the heap and unflattening.

In addition, writeBitmap now records the width/height first in
all cases. If now SkBitmapHeapReader is attached, but an
SkBitmapHeap was used to record the bitmap, reading will fail
and provide the same red SkBitmap as in the case where the
SkBitmap was encoded but could not be decoded.

Updates the PICTURE_VERSION as well.

The key differences in this CL to look at are in:
SkOrderedWriteBuffer,
SkOrderedReadBuffer,
and SkPicture.
