- /* The following two members are used to minimise the amount of unnecessary
- drawing caused by cursor movement. Whenever any drawing affects the
- part of the screen where the cursor is, the cursor is removed first and
- then the drawing is done (this is what the sprite routines test for).
- Afterwards, however, we do not replace the cursor, even when the cursor
- is logically being moved across the screen. We only draw the cursor
- again just as we are about to send the client a framebuffer update.
-
- We need to be careful when removing and drawing the cursor because of
- their relationship with the normal drawing routines. The drawing
- routines can invoke the cursor routines, but also the cursor routines
- themselves end up invoking drawing routines.
-
- Removing the cursor (rfbUndrawCursor) is eventually achieved by
- doing a CopyArea from a pixmap to the screen, where the pixmap contains
- the saved contents of the screen under the cursor. Before doing this,
- however, we set cursorIsDrawn to FALSE. Then, when CopyArea is called,
- it sees that cursorIsDrawn is FALSE and so doesn't feel the need to
- (recursively!) remove the cursor before doing it.
-
- Putting up the cursor (rfbDrawCursor) involves a call to
- PushPixels. While this is happening, cursorIsDrawn must be FALSE so
- that PushPixels doesn't think it has to remove the cursor first.
- Obviously cursorIsDrawn is set to TRUE afterwards.
-
- Another problem we face is that drawing routines sometimes cause a
- framebuffer update to be sent to the RFB client. When the RFB client is
- already waiting for a framebuffer update and some drawing to the
- framebuffer then happens, the drawing routine sees that the client is
- ready, so it calls rfbSendFramebufferUpdate. If the cursor is not drawn
- at this stage, it must be put up, and so rfbSpriteRestoreCursor is
- called. However, if the original drawing routine was actually called
- from within rfbSpriteRestoreCursor or rfbSpriteRemoveCursor we don't
- want this to happen. So both the cursor routines set
- dontSendFramebufferUpdate to TRUE, and all the drawing routines check
- this before calling rfbSendFramebufferUpdate. */
