Summary: no ColsAtCompileTime in Eigen::Transform, needed by inverse_impl

VC10 compilation errors

The below code produces some compile time errors, of which this is probably the most important one:

1> bla\eigen\src/LU/Inverse.h(300): error C2039: 'ColsAtCompileTime' : is not a member of 'Eigen::Transform<_Scalar,_Dim,_Mode>'

The required information is available however, but not in Transform::ColsAtCompileTime, but in Transform::MatrixType::ColsAtCompileTime

The other errors look like they are being caused by the same problem.

Complete error in attachment.

#include <Eigen/Core>
#include <Eigen/Geometry>

Eigen::Matrix4f inverse(Eigen::Matrix4f& mat){
	return mat.inverse();

int main() {

	Eigen::Matrix4f transformMatrix;

	// does not work
	auto invMatrix = transformMatrix.inverse();
	Eigen::Affine3f aff(invMatrix);

	// works as expected
	Eigen::Affine3f aff2(inverse(transformMatrix));
