This function did a const_cast internally which made the call side look
"safe". This method is removed completely and call sites are replaced
with ByteBuffer::wrap(const_cast<void*>(data), size) which makes the
behaviour obvious.
Since the current image handling APIs don't provide a way to handle a
file which can contain multiple images, we just pick the largest one.
This gives the best chance of a good looking result.
This add support to the ICO file decoder for loading uncompressed bitmap icon files.
It is limited to 32-bit color icons, no 4/8/16 bit or paletted formats yet.
This is in addition to the PNG compressed ICO format support added previously.
With this we can now load the favicons for github, google and twitter.
This adds support for loading the first image from ICO format images only if they are PNG encoded.
This is useful for loading favicons, which are sometimes PNGs with an ICO extension and sometimes actual ICO files.
In particular we can now load the favicon from new.ycombinator.com
