Subject: [PATCH] v0.3.4a: re-added align methods pt.1

I realize that aligning to pixel values is important, removing these in 0.3.1d was a mistake. However, previously they were aligning to integer values. not just real pixels. Hopefully this will result in proper alignment without incorrect spacing.
