      Description

      Regression compared to Qt 5.2.1

      Using Mac offline enterprise installer (iOS/android) #21

      Canvas on iOS are just black. Try for example the Qt Quick Canvas example (attached screenshot) or the simple test case below.

      Test case:

      import QtQuick 2.2
      import QtQuick.Controls 1.1
      
      ApplicationWindow {
          visible: true
          width: 640
          height: 480
          title: qsTr("Hello World")
          Canvas {
              anchors.fill: parent
              onPaint: {
                  var ctx = getContext('2d')
                  ctx.save()
                  ctx.beginPath();
                  ctx.strokeStyle = '#FF0000'
                  ctx.lineWidth = 5
                  ctx.translate(50, 50)
                  ctx.moveTo(0, 0)
                  ctx.lineTo(500, 500)
                  ctx.stroke()
                  ctx.closePath()
                  ctx.restore();
              }
          }
      
      }
