TO: SGI Performer developers and
    All who are interested in geocentric terrain models

When will Performer provide access to double precision in both
modeling and matrix operations similar to those in OpenGL (glRotated,
glTranslated, glLoadMatrisd, glMultMatrixd, etc.)?

We are developing a "real" world simulation system using a geocentric
coordinate system and, therefore, require the accuracy of double precision.
Currently, we are applying an offset to our terrain database in order to gain
a few decimal places in floating point precision.
