The original patch courtecy of IRC user grib. The original comment:
Try to coordinate using windows bitmap fonts in the MacFontManager needs to consider
pixels, points, and DPI
Font sizes are usually described in terms of "point" sizes, and rendered
as a number of pixels.
Windows fonts and Macintosh fonts used different DPI (dots per inch).
Bitmap fonts on Mac mostly used 72 dpi, so 72-point font would be about 72 pixels high.
Windows bitmap fonts mostly assumed 96 dpi, so a 72-point font would be 96 pixels high.
director:trektech loads a Windows bitmap font file that is nominally 12 point at 96 dpi. It is 14 pixels high.
Since we cache windows an mac fonts, this ensures that we check both caches
before attempting to generate substitutes, whuch affects greatly
performance in Windows Director games
Disabled menus can still be opened. Menu items in disabled menus will
look and act as if they were individually disabled. Enabling the menu
will restore it to its pre-disabled state.
The LucasArts SCUMM games need to know when this happens so that they
can turn the screen black. Polling the window manager for the menu
status probably wasn't good enough, because it seemed there were cases
where the menu was both activated and opened too quickly for the game to
have a chance to register it happening.
There is no callback for when the menu is deactivated. I could be wrong,
but I don't think this is quite as sensitive?
Previously, every palette change in a game get passed on to the Mac
Window Manager, which would then have to look up new colors for drawing
Mac GUI stuff. This was fine for some games, but later ones do a lot of
palette animations, which could slow things down.
Now the Mac Window Manager gets the new palette only when it's about to
draw the Mac menu, or when it's about to draw a dialog (since those can
be triggered outside of the menu).
Additionally, the Mac Window Manager now triggers the auto-opening of
the menu in the event handler, not in the drawing code. Otherwise the
menu would be drawn once before the SCUMM Mac GUI could notice that the
menu was visible, causing an ugly color glitch.
This flag prevents Mac fonts substitutions with equivalent TTF fonts.
Of course, being this a flag, it will not impact any previous game using
this. It will only impact whichever engine will decide to set it to active
(in our case, SCUMM).
As part of fixing a graphical glitch in Mac Indiana Jones and the Last
Crusade, eliminate the menu timer from the Mac window manager. It's just
too unpredictable and error prone for my taste.
