Merge lp:~townsend/compiz/fix-semi-max-gap into lp:compiz/0.9.12

[Christopher Townsend]

Grid plugin: Float to int division truncating caused a 1 px gap on the right side of right semi-maximized window when the workspace has an odd width. Fix is to add 0.5 to the float division first to account for any truncation error.
