Regression in t3lib_iconWorks::imagecopyresized
Revision 98f73d8b (issue #26660, review ) introduced 2 regressions. One in
t3lib_stdGraphic::imagecopyresized and the second one in t3lib_iconWorks::imagecopyresized.
First regression was already fixed in master  and v.4.7  but the second one is still there. The problem itself is really no brainer - underlying function is called with wrong parameters.
This has to be fixed in 4.7 branch and master (6.0).
The original patch wasn't merged yet to 4.5 and 4.6, so bug can be fixed there.
