0.95: MNG animations not playing, even though they can be read.

[Himekaidou]

XnView: MP 0.95 - 64 bit
OS: Windows 10 64-bit

MNG animations will load and display the first frame only, instead of animating. The properties box in the browser detects the correct total number of frames though.

I have attached two sample MNGs that are animated to test with, if need be.

Effect: MNG animations do not play.

To reproduce:
1. Try to preview the MNG in either XnViewMP's browser, or by opening it fully.

Actual behaviour (bug): The animation does not play, it only statically shows the first frame.

Expected behaviour: The animation plays normally.
