Help routine to decompose given homogen 3x3 matrix to components.

Decomposition.

A correction of the components is done to avoid inaccuracies.

See basegfx::utils::createScaleShearXRotateTranslateB2DHomMatrix() for the opposite, to compose a homogen 3x3 matrix from components.

New, optimized version with local shearX detection. Old version (keeping below, is working well, too) used the 3D matrix decomposition when shear was used. Keeping old version as comment below since it may get necessary to add the determinant() test from there here, too.
