* @brief initialize pointer cursor with custom handling
|
|
*
|
|
* For DDX'es that need their own handling of pointer cursors,
|
|
* and can't use the generic "soft cursor" that's created via
|
|
* miDCInitialize().
|
|
*
|
|
* That can be the case on certain video HW with it's own sprite support,
|
|
* or on remote display protocols like RDP, where the client get the cursor
|
|
* pixmaps sent over the wire and is responsible for painting it on his side.
|
|
*
|
|
* Overwrites ScreenPtr vectors:
|
|
*
|
|
* ConstrainCursor, CursorLimits, DisplayCursor, RealizeCursor,
|
|
* UnrealizeCursor, SetCursorPosition, RecolorCursor, DeviceCursorCleanup
|
|
* DeviceCursorInitialize
|
|
*
|
|
* Hooks to ScreenPtr vectors: CloseScreen
|
|
*
|
|
* @param pScreen pointer to ScreenRec the pointer handling applies to
|
|
* @param spireFuncs pointer to miPointerSpriteFuncPtr call vectors
|
|
* @param screenFuncs pointer to miPointerScreenFuncPtr call vectors
|
|
* @param waitForUpdate TRUE if MI shouldn't redraw the pointer immediately,
|
|
but wait for somebody else triggering it explicitly
|
|
* @return TRUE on success, FALSE usually indicates allocation failure
