From Panagiotis Koutsourakis, "We are using Open Scene Graph for an application and we need COLLADA

support. While testing the pluggin we found a small bug and we are
submitting a patch.

The first attachment is a small program that creates a scene with two
pyramids, transformed by two instances of
osg::PositionAttitudeTransform. One of them is rotated 90 degrees in
the X axis, and the scene is exported both in the native OSG (.osg)
and COLLADA (.dae)  formats. In the first case the rotated pyramid is
displayed correctly whereas in the second the pyramid seems not to be
rotated.

In the COLLADA 1.4.1 specification (found at
http://www.khronos.org/collada/) it is specified that
"The <rotate> element contains a list of four floating-point values
[...] followed by an angle in degrees" but the plugin seems to write
the value in radians.

The problem seems to be in the method daeWriter::apply() that seems to
be writing the angle value in radians to the COLLADA file. The patch
can be found in the second attachment and is simply a call to
RadiansToDegrees wrapped around the angle.
