Use xcb_cursor library instead of Xlib based one in Cursor
Review Request #122290 - Created Jan. 28, 2015 and submitted - Latest diff uploaded
Straight forward port from XLib based XCursor library to the
xcb variant which is considerably new. The xcb variant only allows
to create xcb_cursor_t for the default theme and size. Which suits
the needs in Cursor quite well, but means it's not a replacement for
the usage in zoom effect.
Tried switching theme and size: works as expected.
