ReaderWriterATTR.cpp had a variable "mips" defined, which is predefined for the IRIX preprocessor.
Changed this to _mips.
FltFile.cpp had a class and transient variable defined within the scope of member function
FltFile::readExternals(), which was causing the IRIX 7.3 compiles to hork. Moved the class
definition to outside of the member function scope.
it consistent with the rest of the osg::Matrix naming. Updated OSG
distribution to account for new name.
Added support for the STATIC/DYNAMIC osg::Transform::Type to the .osg
ASCII reader/writer plugin and the flt reader plugin.
Removed the non cost version of osg::Transform::getMatrix() as this could
by pass the dirty mechinism.
