public void setDepthBits(int value) {
        putInteger("DepthBits", value);
    }
Sets the number of depth bits to use.
<p>
The number of depth bits specifies the precision of the depth buffer.
To increase precision, specify 32 bits. To decrease precision, specify
16 bits. On some platforms 24 bits might not be supported, in that case,
specify 16 bits.<p>
(Default: 24)

@param value The depth bits
