@{b}    NAME@{ub}
	CalcViewModes() -- Calculate Amiga-specific ViewModes from a BMHD

@{b}    SYNOPSIS@{ub}
	viewmodes = CalcViewModes( bmhd )
	D0                         A0

	ULONG CalcViewModes( struct IFFL_BMHD )

@{b}    FUNCTION@{ub}
	Tries to calculate the viewmodes for a CAMG chunk by looking at
	the bmh_Width, bmh_Height and bmh_Depth entries of a bmhd.
	This is not always satisfactory, but we're stuck with it.

@{b}    INPUTS@{ub}
	bmhd - @{"BitMapHeader" Link "INCLUDE:datatypes/pictureclass.h/Main" 94} describing the picture's dimensions

@{b}    RESULT@{ub}
	viewmodes - ULONG containing the view modes (LACE, HIRES)

@{b}    BUGS@{ub}
	Knows nothing about Monitor IDs or new @{"View" Link "INCLUDE:graphics/view.h/Main" 63} modes like SUPERHIRES
	or HAM8. You should not use this function in new code.

@{b}    SEE ALSO@{ub}
	IFFL_GetViewModes(), IFFL_SaveClip()
