+Description: Enforce types supported by spec for QColor
+ This patch fixes a bug in Manuskript relating to argument types passed to
+ QColor. A couple spots in the code were possibly passing floating-point values
+ to QColor rather than integers, which was causing a crash when the user
+ attempted to launch Manuskript.
