Hi,

i'm working on modifying the code to adress the comments (ENABLE_WEBP=0, USE(), tabs, layout tests...).
I'll submit a revised patch soon.

Meanwhile i just want to rebound on the signature issue: i was told that one should use the minimal number of bytes that would rule out most of bad cases. Since most of other image formats were only using 4 bytes (and even, only 2 for BMP format!), i thought about using the same length and only probe for "RIFF". The real probing would use 12 bytes and check for "RIFF????WEBP", but i was under the
impression this was too long a look ahead to ask for. Isn't it?

thanks,
Pascal
