For non-recorded stateblocks a light always exists in the device stateblock as
well, since that's where it's copied from. However, when SetLightEnable() is
called for a light that didn't a exist yet while recording a stateblock, the
light is only created on the recorded stateblock.

ole2: Convert the icon for OleMetafilePictFromIconAndLabel to 32-bit explicitly instead of casting the handle.

winex11: Don't process ConfigureNotify events that have been superseded by a later configure request.
