PSYCHTOOLBOX SPECIFIC single() implementation:

retval = moglsingle(arg) -- convert into
a single precision floating point number.

This routine takes an 'arg' of arbitrary
numeric class and converts it into an equivalent
object of single precision floating point format.

If a builtin single() function is available,
as on Matlab and Octave 3.2+, it calls the builtin
single() function.

Otherwise (Octave) it would call our own special
implementation.

This is no longer needed as of Octave 3.2.0, but we leave the function
here as many internal and external code relies on its presence.

For Octave pre 3.2, this applied:

This is a hack needed to make OpenGL (MOGL) work
on GNU/Octave, despite Octave's lack of a single
precision data type. Returned values are not
useful or accessible by Octave. They only have
meaning for the Psychtoolbox OpenGL functions.
