The observatory go button computes random 105x106 rectangles in the
512x512 star image. The previous code would allow to go out of bounds by
3 pixels. Interestingly the bug is in the original engine disassembly
perhaps it could crash as well.
Fixes Trac#10576.
Fixes Trac#10572.
The day slider does not go all the way to the bottom (day 31st)
when the down arrow is used to increment the day. This change
increases how much y displacement happens with each change
in the day so that the bottom is reach on day 31st.
This is just a graphical bug and doesn't affect the logic
of the puzzle. The day slider can also be dragged to the bottom
without using the buttons.
When the lights are on, the open door image would not draw at the
correct position in Myst ME only.
This is due to the open door image being too small. The original has a
special case for that image. We reproduce that same hack.
Fixes Trac#7143.
With the addition of autosaving support, deleting saves
(via the gui) to slot 0 was disabled, but for saves that
have been previousl created by the user it make sense
that they should be allowed to delete a save in slot 0.
Fixes Trac#10536.
The previous logic was enabling autosaving if the metadata
file was not present, but saves from the original
don't have metadata. Now it checks if the non-metadata
file can be loaded to determine if the slot is empty.
The game will autosave to slot 0 using the save
period given in the scummvm config file.
Or when the user quits.
Autosaves are only allowed when an autosave is
in slot 0, there is no save in slot 0, or there
is a save, but it is corrupt.
This will not override any saves the player
has previously put in save slot 0. If there
is a save in slot 0 that is not an autosave
then there will be no autosaving.
The game will autosave to slot 0 using the save
period given in the scummvm config file
or when the user exits using the GMM.
