Do not re-create font if it is not of TMPF_TRUETYPE

Browse Source 
For !ttf and stretch==100 case, it was:
hfont = CreateFontIndirect(&lf);
TEXTMETRIC tm = ..;
if (!ttf) {
    DeleteObject(hfont);
    lf.lfWidth = tm.tmAveCharWidth;
    hfont = CreateFontIndirect(&lf);
}
Unless there is some special behavior for non-TrueType fonts I don't
know about, it looks to me like a 100% waste.
