NAME
    CWAIT -- Append copper wait instruction to user copper list.

SYNOPSIS
    CWAIT( c , v , h )

    CWait( c , v , h )
           a1  d0  d1
    CBump( c )
          a1

    void CWait( struct ucoplist *, word, word)

FUNCTION
    Add instruction to wait for vertical beam position v and
    horizontal position h to this intermediate copper list.

INPUTS
    c - pointer to ucoplist structure
    v - vertical beam position (relative to top of viewport)
    h - horizontal beam position

RESULTS
    this is actually a macro that calls CWait(c,v,h)
    and then calls CBump(c) to bump the local pointer
    to the next instruction.

BUGS
    User waiting for horizontal values of greater than 222 decimal
    is illegal.
