The msys shell can be run in both msys and in mingw mode. We don't
support it when in msys mode, as this mode seems to be intended as a
cygwin-like compatibility layer, instead of for native Windows
applications.
Some backends like GCW0 do no support graphics >320x240 due to
the hardware limitation (downscaling is possible but it will ruin
the pixel hunting which is often part of the gameplay).
Instead of manually updating the list of engines, we now introduce
a new dependency.
I marked all relevant engines, but some, like tinsel, require more
work with putting their relevant high-res games under USE_HIGHRES
define.
(Look https://sourceforge.net/p/scummvm/bugs/6980/)
The warning messages were appearing because when PRECACHE_RESOURCES is
not defined, ResourceManager's `requestResource()` was used to manually
"cache" them. When you do that, ResourceManager "locks" the resource
once, so you must `release()` it later.
Resources were not released, and warnings appeared. When you
`release()` resource, it still is loaded ("cached"). Resource's
`getLockCount()` is 0, though, so it might be unloaded by
ResourceManager if there is a lot of resources.
The original engine had some members on PlaneShowStyle to
allow wall clock timing but never actually used them in the
processing loop so transitions simply ran as quickly as the
CPU could process them. For the moment, we will just limit
these transitions to ~30fps, which hopefully roughly matches
the speed of the engine on hardware of the era.
Causes issues in at least gk1 (option + inventory plane are shown)
Game::restore is not called, when doing restores from launcher,
so in the original interpreter this script code wasn't called
either.
Fixes option + inventory planes etc. being shown right after
restoring via launcher, when original save/load dialogs were
disabled.
Adding consts to try to isolate rectangles that change during
draw list processing, to be investigated for incorrect mutations
causing lower screen items to be drawn over higher screen items at
their edges.
