Yes, glyphs with outline (in other words, glyphs that draw some black
pixels) contain width and left sidebearing information. Page 50 of
Black Book ('Adobe Type 1 Font Format') says:
	Either sbw or hsbw must be used once as the first
	command in a character outline definition.
Most font use 'hsbw' command, which takes two arguments, (horizontal)
left side bearing and width.

But space does not draw anything and contains no outline, so AFM
is needed besides PFB.

The width is set to 269 (WX is the advance width of glyph 

A bounding box is the smallest rectangle that contains whole
outline of the glyph. White space charecters does not draw
anything, so BBox is set to '0 0 0 0' eventually.
