Summary: SAGA: compile warnings

Initial Comment:
With the latest CVS snapshot, I get the following
warnings - repeated several times - while compiling the
SAGA engine with GCC 3.4.2:

./saga/gfx.h:39: warning: ignoring packed attribute on
unpacked non-POD field `Common::Rect
Saga::ClipData::sourceRect'
./saga/gfx.h:40: warning: ignoring packed attribute on
unpacked non-POD field `Common::Rect
Saga::ClipData::destRect'
./saga/gfx.h:41: warning: ignoring packed attribute on
unpacked non-POD field `Common::Point
Saga::ClipData::destPoint'
./saga/gfx.h:44: warning: ignoring packed attribute on
unpacked non-POD field `Common::Point
Saga::ClipData::drawSource'
./saga/gfx.h:45: warning: ignoring packed attribute on
unpacked non-POD field `Common::Point
Saga::ClipData::drawDest'

The ClipData struct is packed, but the way I read these
warning messages we still cannot make any assumptions
about the size and exact layout of it. This could be
bad, but on the other side I'm not sure I can see
anywhere where the clip data needs to be packed...

I haven't checked if the other two structs that are now
packed, PalEntry and Color. They don't contain any
unpacked members. We still can't make any assuptions
about Color, though, since it uses the "int" data type.
