    Description

      It seems there is a deep copy happening in toVGImageSubRect() , because of a call to non-const version of Qimage::bits().

      There are some more functions which calls non-const version of Qimage::bits() function in OpenVg paintengine code:

      1. toVGImage()
      2. toVGImageWithOpacity()
      3. QVGFontGlyphCache::cacheGlyphs()
      4. QVGCompositionHelper::drawCursorPixmap()
      5. toVGImageWithOpacitySubRect()
