SetMapMode sets the mapping mode to one of MM_TEXT, MM_LOMETRIC,MM_HIMETRIC,
MM_LOENGLISH,MM_HIENGLISH,MM_TWIPS,MM_ISOTROPIC,MM_ANISOTROPIC<br>
Set <a href="mapmode.html">this doc</a> for explanation<p>
Id like to point out here, that some wmf files do not set a mapping mode at
all, and while the referenced doc here puts MM_TEXT as the default mapping
mode, in practice when no map mode is set <b>and</b> the wmf isn't a
placeable wmf, i.e. there is no information at all about the desired size of
the wmf, then this is a problem because <br>
<ul>
<li>wmfs exist which expect to be played in MM_TEXT mode where each unit is a pixel and<br>
<li>wmfs exist which expect to be played in MM_TWIPS mode where each unit is 1/1440 or
an inch.<br>
</ul>
and neither set a MAPMODE. (grrr) so arbitrarily i put non-placeable wmf files
that have no MAPMODE set into MM_TEXT mode if they are < 400 x 400 and into
the other mode if they are not.
