Description Michael Smirnov 2008-11-21 08:21:23 UTC 
Please describe the problem:
y0 parameter of the resulting matrix is calculated incorrectly:

matrix->y0  = tmp.yx * new_matrix->y0 + tmp.yy * new_matrix->y0 + tmp.y0;

but it should be:

matrix->y0  = tmp.yx * new_matrix->x0 + tmp.yy * new_matrix->y0 + tmp.y0;

Steps to reproduce:
