Enable loading of broken truncated GIFs
This updates libnsgif (by running subprojects/libnsgif/update.sh
) to:
Upstream: https://source.netsurf-browser.org/libnsgif.git
Ref: fa1f47e6bec71ed970a02a517056fac677256c9d
It also adds a call to nsgif_data_complete()
, which allows truncated GIFs to be loaded.
