Quesa patch for partial 64 bit support on Mac OS X

[Sean M. <se...@ro...>]

Hi all,

So we've just downloaded Quesa CVS and tried to build it as 64 bit.  Not
sure if we're the first to try... it doesn't compile.  :)

Attached is a patch that fixes almost all compilation issues.  Could
someone review it?

Most changes are pretty straightforward.  Some comments:

a) QUESA_SUPPORT_QUICKTIME is forced to 0 in 64 bit.

b) Added a QUESA_SUPPORT_QUICKDRAW that is analogous to
QUESA_SUPPORT_QUICKTIME.  It must be 0 in 64 bit since QuickDraw/
HIToolbox is gone.  Changed some QUESA_OS_MACINTOSH to
QUESA_SUPPORT_QUICKDRAW.

c) Removed FSSpec usage in 64 bit.

d) various casts, tweaks, etc.

Note that I have only compiled this on Mac OS X, no other platforms.

Note that even with this patch, there are still compiler errors in 64
bit (but not in 32 bit).  The remaining errors I am not comfortable
fixing because it requires a better knowledge of Quesa than I have.  I
thought I'd start with this patch before discussing remaining problems....

Lastly, I realise that removing the QuickDraw/HIToolbox usage in Quesa
means that it will be missing major functionality.  In our case however,
we only need a small subset of Quesa and are happy to report that that
subset runs just fine in x86_64!

Cheers,
