You're right. This problem was introduced through my switching screenshot
glReadPixels from RGBA to RGB.
However, setting the PACK size to 1 will probably hurt performance, probably by
as much as a factor of 4. I'll rewrite this to properly take into account
paddings at the end of lines. This is probably the best solution. This will
also allow for higher PACK sizes which is probably alot more efficient if the
bus to the graphics card allows for it, but that's something that is up for
testing. :)
