wolfbeast	a1c22f3a76	Check for contiguous buffer state. ... When we are reading large image data (i.e.: people using webp to stream video instead of the native webm format; I'm looking at you, Giphy!) we can run into the situation where the available data is not in a contiguous buffer, and we need to either buffer additional data or re-buffer from the start. If we don't do this, we can run into issues because of buffer over-reading (causing corrupted data if allocated or more likely crashes if not allocated). Re-buffering is expensive, but this should be rare and limited to dealing with unintended use for animated image formats. This resolves #940.	2019-02-16 00:24:38 +08:00
