--- Comment #37 from phaethon eriks00@moon.lv --- Most likely your solution is superior. I noticed working with Photoshop if these values are 0 initially, they stay as zero, otherwise Photoshop sets them to sensible value. If these stay as 0, then pkX and pkY are scaled to 0 in the message. So, setting to anything was better than initializing with 0.
Did you submit your patch? If yes, what was its fate?
