Openjpeg was modified: "p_max_len -= l_nb_bytes_read;" was causing an overflow.
I'm not sure if I did something incorectly in opj_skip/opj_seek viewer side, but seems like openjpeg should have been checking remaining space in p_max_len either way.
P.S. Many thanks to Chafey and Neopallium for implementing openjpeg's partial bitstream support

SL-18151 [SEC] MOAP can force multiple floaters open on users screen: The Viewer part of the fix for this JIRA - pulls in the updated Dullahan that exposes the user_gesture/is_redirect flags and uses them to determine what type of 'nav_type' is exchanged with viewer/plugin

Don't add popup to the list twice

Make notifications modal. When multiple ones are visible, first popup works, interacting with second one causes a crash. And it shouldn't be possible to change anything in floater when these notifications are visible

Viewer was drawing empty "indicator_stack" over description
