There were changes made to original Konqueror graphics in#632.  These werequestionable in that: a) they were an instance of fixing something that wasn'tbroken; and b) editing was highly unskillful and came from a contributor thatalso used AI to generate new wallpaper in TDE.Some of these editing issues were later corrected in#649, but the texture stillexhibits transparency issues.This commit reverts the texture to its original state, which had no issues thatneeded fixing.See tdeartwork#58
