// .NAME vtkQtLabelRenderStrategy - Renders labels with Qt
//
// .SECTION Description
// This class uses Qt to render labels and compute sizes. The labels are
// rendered to a QImage, then EndFrame() converts that image to a vtkImageData
// and textures the image onto a quad spanning the render area.
