- test that:
- the last error is never set
- the buffer size is ignored if the buffer is NULL
- the buffer size is returned if the buffer is non-NULL and too small
- the function fails if a non-NULL buffer has a size <= 0
- allocate the DC for a GDI test with a GDI routine (CreateCompatibleDC) instead of an USER routine (GetDC)
