I have just done a board with a 48 LQFP placed at 45 degrees and had no problems. I did use the finest grid resolution to route the tracks upto the chip. Perhaps there is something strange you are doing? About the zone fill, it is a simple zone fill and not, shall we say, a copper pour. To get good results you should first draw a track (wide if possible) around the area you want to fill and then put the 'edge' of the zone in the middle of the track. When you fill the zone you can select the size of the track to be used (KiCAD does not yet select this automatically). You should use the largest size that gets good results (that is the jagged edges are contained inside the delimiting track). As for professional suitability, like I said, I got fine results. Perhaps the biggest problem would be if you are trying to quite literally plot the board using a pen plotter, here lots of overcrossing lines can be a problem. As for a phottoplotter it is enougth that the area gets exposed, and you can see clearly what your results will be. Note also that many of the more serious PCB producers will be using software which optimises the photoplotting.
