QSGDefaultRectangleNode: Fix off-by-one color rendering
Implicit conversion from floating-point to int, which simply truncates
the number's fractional part, may have caused the rectangle fill
to be rendered in a color with some of its RGB components different
by ±1 from the specified value.
For example, the actual on-screen color of the following QML item was
#010101 on 32bit Intel (no antialiasing or alpha channel):
Rectangle {
width: 100
height: 100
color: '#020202'
}
This commit improves precision of the calculation by applying qRound()
before the conversion to integer.
