Commented some logging that could be '''very''' long, cuts -vv output size of a gtkd gl sample down 1.2GB by 3/4. Fixed wrong pointer type for multidimension "deep" slicing.

module complex2;

void main()
{
    cdouble c = 3.0 + 0i;
    cdouble d = 2.0 + 0i;
    cdouble c1 = c + 3.0;
    cdouble c2 = c - 3.0i;
    cdouble c3 = c / 2.0;
}
