Some adjustments to make view elements clearer and more correctly sized, especially on hidpi (non-pixel-doubling) systems

 
     QSize imageSize = size() * devicePixelRatio();
     m_cache = QImage(imageSize, QImage::Format_ARGB32);
     m_cache.fill(Qt::transparent);
 
-    double w = m_cache.width();
-    double h = m_cache.height();
-
+    int w = m_cache.width();
+    int h = m_cache.height();
     int bw = 3; // border width
 
     QRect subclip;
     if (m_orientation == Qt::Horizontal) {
         subclip = QRect(bw, bw+1, w - bw*2, h - bw*2 - 2);
