scroggo@google.com 284bf502c0 Purge bitmaps from SkGPipe's shared heap. ... BitmapInfo: Now in SkGPipePriv so it can be accessed by SkGPipeRead. Add the ability to essentially ref count BitmapInfos so that they can be purged to make room in the shared heap for a new one. SkGPipeWrite: Purge the least recently used bitmap if it has already been drawn by all readers. SkGPipeRead: Read the BitmapInfo (instead of the SkBitmap) and decrement its count after drawing. SkGPipeController: Added a method to tell how many readers will be used, so that when purging bitmaps each reader can be accounted for.
