Attached to this mail are a couple of patches that should fix some
issues with mouse cursors. It would be nice if some people could have
a look and see if the patches break anything. Patches 1-4 move cursors
into the server, 5 adds support for Xcursor cursors, 6 & 7 are
cleanups, 8 fixes loading of .cur cursors, 9 adds support for animated
cursors and 10 adds support for 32bpp cursors.


Overall, I'm very impressed with the patch set.

However, I did find two things that I think need consideration or improvement:

From 01_server_cursoricon.diff.txt:

+/* Destroy a cursor */
+DECL_HANDLER(destroy_cursor)
+{
+    unsigned int i;
+    cursor_t *cursor = free_user_handle( req->handle );
+
+    if (!cursor) return;
+
+    for (i = 0; i < cursor->num_frames; ++i)
+    {
+        if (cursor->frames[i].bits) free( cursor->frames[i].bits );
+    }
+
+    free( cursor->frames );
+}


This appears to be the only place where a cursor is destroyed. Thus, a bad application could end up wineserver to leak memory. I think you need to investigate when Windows frees cursors that have not had DestroyCursor called on them. My guess is that it frees them on process destruction.


From 09_user_ani_cursor.diff.txt:

I'm not sure it is acceptable to import winmm from user32, even if it is a delay import.
