[TIMOB-722] height/width auto on a label = blurry text

Issue appears to show up when using odd width (or height) values, which sets the center point of the label on a fractional value. This seems to have the same effect as having the origin point on a fractional value - text is presented 'blurred'.

We handle this by rounding the center point to its nearest integer value for text display (something which [UILabel setFrame:] seems to do on its own).

(from [c21b7ca945bc2b6fc5e60f91028ede80d7451604]) Closes #722. Force UILabels to be centered on integer values. http://github.com/appcelerator/titanium_mobile/commit/c21b7ca945bc2b6fc5e60f91028ede80d7451604"> http://github.com/appcelerator/titanium_mobile/commit/c21b7ca945bc2...

Hi,

See my comment on this thread - I am still seeing some inconsistency with the anti-aliasing/blurring when labels are used in a tableView within a vertical layour view in each row.

See my comments on #539. TableRowViews may require special code to prevent blur due to dynamic loading. This should be considered a separate issue.
