[ft-devel] patch to use of enums in ft2demos

[Steve Langasek]

Hi all,

GCC 4.5 emits a new warning when an enum type is compared to a numeric
constant whose value isn't included in that enum.  Since there's a bit of
that going on in ft2demos, this results in a build failure with -Werror,
with errors such as the following:

gcc-4.5 [...] -Werror [...] src/ftdiff.c
cc1: warnings being treated as errors
/home/devel/freetype/freetype-2.4.2/ft2demos-2.4.2/src/ftdiff.c: In function 
'process_event':
/home/devel/freetype/freetype-2.4.2/ft2demos-2.4.2/src/ftdiff.c:1074:5: error: 
case value '43' not in enumerated type 'grKey'
/home/devel/freetype/freetype-2.4.2/ft2demos-2.4.2/src/ftdiff.c:1067:5: error: 
case value '45' not in enumerated type 'grKey'
/home/devel/freetype/freetype-2.4.2/ft2demos-2.4.2/src/ftdiff.c:943:5: error: 
case value '49' not in enumerated type 'grKey'

There are two possible ways to address this:  we can extend the enum to have
a full list of the values we care about, or we can avoid defining variables
to use the enum type when that's not actually how it's being used.  I think
the latter solution makes more sense here, but I have no strong opinion, so
I've attached a patch for each option.

Cheers,
