This update fixes:
- User interface paint issues (blank/empty controls and address bar) that would occur in some cases when viewing standalone images.
- Excessive processor usage in some cases when viewing standalone images.
- Slow thumbnail creation when viewing standalone images.
- Thumbnails will be created for (much) larger sized images. There is still a limit and excessively large images will not be processed, but most images will have a thumbnail drawn now.
- Lower processor usage.
- The address bar shows a generic graphics icon instead of the thumbnail when viewing an image file; thumbnails will only be shown in the tab header.
- browser.chrome.image_icons.max_size no longer has an effect, with the exception of setting it to 0 - this will disable thumbnail creation.
The preference is still used, but only if the browser for whatever reason is unable to draw the thumbnail with the new method, in which case it will fall back to the previous (Firefox-equivalent) method.
- Completed consolidation of the source tree -- from this point forward, there won't be separate source trees for different architectures anymore.
