[PATCH xserver v3 23/24] xwayland: Cut off upper 32bit of queued vblank delay

2018-03-13 Thread Roman Gilg
This ensures the same behavior as in Present's fake counter and xfree86. At the moment clients might do put vblanks too far into the future, because the fake vblank code in Present and the xfree86 driver tolerate cut off upper 32bit due to an 64 to 32bit conversion. Do this therefore here as well
