XXXXmmmmeeeeFFFFrrrroooommmmHHHHoooorrrriiiizzzzoooonnnnttttaaaallllPPPPiiiixxxxeeeellllssss converts a horizontal pixel value to
a real-world dimensional unit. The real-world dimensional
unit depends on the value of the XXXXmmmmNNNNuuuunnnniiiittttTTTTyyyyppppeeee resource
associated with the widget. For example, suppose _w_i_d_g_e_t has
an XXXXmmmmNNNNuuuunnnniiiittttTTTTyyyyppppeeee resource value of XXXXmmmm1111000000000000TTTTHHHH____IIIINNNNCCCCHHHHEEEESSSS. If the
input _v_a_l_u_e were 200 pixels, the output _v_a_l_u_e might be 2500
(2.5 inches) on one screen and 2000 (2.0 inches) on another
screen.

Typically, your widgets will call this function in a
synthetic resource record.
_w_i_d_g_e_t Specifies the widget.
_o_f_f_s_e_t Specifies the offset (in bytes) of a synthetic
resource field in the widget record.
_v_a_l_u_e Specifies a value in pixels and returns a value in
the dimensional units used by _w_i_d_g_e_t.
