function RequestRendering();

Invalidate() simply causes the window to be repainted at the system level. It does not make PDFViewCtrl to render anything new. RequestRendering() tells PDFViewCtrl to check if there are regions (both visible and invisible) that have not been rendered; if so a background rendering thread will be started. This function should be called if CancelRendering() was called to stop the ongoing rendering thread. Update() tells PDFViewCtrl to discard the rendered content and start a rendering thread. This function should be used if the content of the PDF is modified.
