Bug 174337 – Bitmap should try to match asynchronously decoded frames for synchronous drawing if possible

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Images

[Said Abou-Hallawa]

Currently we assume if an image has been drawn asynchronously, it will never been drawn synchronously after that. The conditions, which controls synchronous versus asynchronous drawing, rely on the settings and the image size. These condition will include soon other things which change at runtime like, for example, an image will be drawn asynchronously only for the first time a tile is painted. But after that the image will be drawn synchronously. So we need to be more efficient and try to use the already decoded frames instead of decoding new ones unnecessarily.
