DGDS: (ROTD) Speech bubbles disappear too quickly at Chen Lu's

[electricsheep82]

On the evening of the first day, when Blade finds Chen Lu's body in his apartment, some of the speech/thought bubbles flash on and off the screen too quickly to read:

When the police dispatcher reports the break in (dispatcher.gif):
"Meanwhile"

When the police arrive and throw Blade in jail (imprisoned.gif):
"Freeze, turkey!!! One move and you're vaporized!"
"Great! Now what am I gonna do?"

When Jonny Qwong talks to the lab technician (lab.gif):
"Meanwhile"

When the police release Blade from jail (bail.gif):
"I wonder why the mayor wants this guy bailed out?"

ETA: looking at the comment on ticket #15775, it seems like it might be useful to include a screen recording of what the timing looks like in dosbox, so I've attached that as well.

ETA 2: added save game just before entering apartment

Thanks for the report, and going to the effort of producing comparison recordings for each one - very useful and saved me a lot of time!

The "meanwhile" problems are the same as #15775, but the ones after fade-in were different. The timer value was started before the fade-in.

I've put in a small workaround for that problem.

In 7dd3f6b7:

DGDS: Update frame timer after fadein/fadeout

Dialog hide times are decided at the end of the frame where they are engaged.
If the frame also had a fade-in or fade-out, the "frame time" is now way off
when the frame actually started, so we need to update it as a small hack to get
the right timing for other events.

This fixes #16519.
