Here is the MetaPost to handle what you're after. I still don't think
it is the right thing to do in 99% of all situations.
% Define macro to scale to a desired width.
primarydef P scaledw W =
P scaled (W/(xpart (lrcorner P - llcorner P)))
enddef;
draw btex {\usefont{OT1}{cmr}{m}{n} $c^2=a^2+b^2$} etex scaled 1.0
shifted (11.00000x,4.650000y);
draw btex {\usefont{OT1}{cmr}{m}{n} Mary had a little lamb.} etex
scaled 1.0 shifted (11.00000x,5.000000y);
draw btex {\usefont{OT1}{cmr}{m}{n} $c^2=a^2+b^2$} etex scaledw 4.0cm
shifted (11.00000x,7.650000y);
draw btex {\usefont{OT1}{cmr}{m}{n} Mary had a little lamb.} etex
scaledw 4.0cm shifted (11.00000x,8.000000y);
