Hello,

There is a problem with OpenCCSG and multmatrix. Compare the results of
the following program when using F5 or F6:

translate([-20, 0, 0]) cube(10);

// Homothecy

b = 2;

multmatrix([

[1, 0, 0, 0],

[0, 1, 0, 0],

[0, 0, 1, 0],

[0, 0, 0, 1/b]

])

cube(10);

I add that this behaviour appears with the 2014.03 version on Ubuntu-Gnome.

On WinXP 32:

2013.06 and 2014.02.25 F6 the second cube gets bigger.

2015.02.20 (git 2cf9de3) it stays the same size.

Another possible correct behaviour would be the second cube is bigger in
both F5 and F6.

Yes, it should be the correct behaviour.
