Since 360d6bf4 the precompiled header for vcl
includes <rsc/rsc-vcl-shared-types.hxx> , so the KEY_SHIFT from there
interfered with the KEY_SHIFT here.

These magic values apparently are the "known" return values from
MapVirtualKey() called to translate (fixed) virtual key codes to scan codes,
suitably shifted and ORed with some flag bit(s). Whether such scan code values
really are constant in all Windows installations I have no idea, it does sound
a bit scary to me to assume they are. (If they are, why does <windows.h> then
not provide symbolic names for them?)
