It now supports arbitrary regions! The tool itself still makes
rectangles, but you can shift-drag to add to the selection.
It also distinguishes visually between a floating selection and not, is
more easily visible against certain tile backgrounds and at small zoom
levels, and, I don't know, probably some other stuff.
You know. Lexy colors. Seems to make sense.
Also fixed several places I just hated the color scheme, such as the
hover color in popup menus and the title bar in dialogs. Woohoo.
The default is now what I /think/ is the Lynx behavior: try to push the
block first, and only give it a pending direction if the push fails.
CC2 always uses the pending mechanism.
Not sure the latter one is even correct at all; it completely breaks
ICEHOUSE, for one. I guess it made more sense with the previous hacky
implementation of force floors applying at the start of the game.
Since sliding happens either on cell arrival or in the actor's idle
phase, the actor will always have a pending slide by the end of a tic,
so this code doesn't actually do anything.
This seems to simplify things and also explain the CC2 semantics: force
floors activate while being stood on (which happens, I guess, during
idle), so it applies to objects that start the level on force floors.
This was probably done to make force floor flipping work, too. On the
other hand, ice still only activates when being stepped on.
This does simplify things a bit, and it also fixes the replay for CC2LP1
level 160, Sneak Around. It breaks three Voting replays, unfortunately,
but doesn't break anything else, so I'm inclined to call it better.
I had it mostly right based on experimentation, but had the conditions
inside-out, which allowed this case to slip through the cracks. This
makes the Settlement of Arrakis replay sync.
