Yeah, we did that, however I'm not sure I agree that we should need to.

Title:
  Text.color can't be compared reliably

Status in qtdeclarative-opensource-src package in Ubuntu:
  Confirmed

Bug description:
  Given the below QML:

  import QtQuick 2.4

  Text {
      id: text
      text: 'foobar'
      color: foobar

      property color foobar: Qt.rgba(0, 0, 0, 0.5)
      property color foobar2: foobar

      Component.onCompleted: {
          console.log("text:", text.color, foobar, Qt.colorEqual(text.color, 
foobar), text.color.a);
          console.log("property:", foobar2, foobar, Qt.colorEqual(foobar2, 
foobar), foobar2.a);
          /*
              qml: text: #80000000 #80000000 false 0.5019607843137255
              qml: property: #80000000 #80000000 true 0.5000076295109483
          */
      }
  }

  Seems that Text.color stores the colour with a different precision,
  resulting in Qt.colorEqual() returning false.
