Fix rounding issue causing border-like artifacts. #8

Closed fanwashere closed 8 years ago

Due to the usage of floor and ceil, some rows and columns of the canvas does not have rects filled in. This seems to be fine with normal colors, but when using opacity (e.g. rgba(255, 255, 255, 0.9)), there border-like artifacts from the rounding.

Changing to round seems to fix this.
