Mouse cursor is not showing, as server is not sending it, until it changes.

Scenario
-Server-

TightVNC Server, version 2.8.27
-Clients-
noVNC client, version 1.1.0
UltraVNC Viewer, version 1.2.40

Steps

Connect
See no cursor icon is displayed.
Click on anything that opens a window.
Cursor suddently appears as it has changed.

As a workaround I am using dot cursor on client side, until the correct one appears as changed.

Same issue with TightVNC server w/ Android AVNC client: https://github.com/gujjwal00/avnc/issues/49

Apparently, TightVNC doesn't send the cursor position until the window changes: https://github.com/novnc/noVNC/blob/master/core/rfb.js#L202
