The refreshWindow() function calls doPaint() from zlibrary/ui/src/gtk/ZLGtkViewWidget.cpp, which is where the actual drawing takes place.

erClientChannel_t erbusyChannel;

Display * display;

static void doPaint(GtkWidget*, GdkEventExpose*, ZLGtkViewWidget *data) {
  // Turn on the busy LED
  busySetBusy(erbusyChannel, ccBusyState_Blink);
  data->doPaint();
  // update eInk display
  display = gdk_x11_display_get_xdisplay(gdk_display_get_default());
  XSync(display, 1);
  dmDisplay(dmCmdPriorUrgent, dmQFull);
  //Turn off the busy LED
  busySetBusy(erbusyChannel, ccBusyState_Off)

That's what I used for the 0.10 binary I posted. Just now updating things for 0.12.7, hopefully will have a new binary to post soon, with pre-rendered pages
