GM_SetPointFeatureClassDrawStyle

Sets the default style and font to use for drawing points with the given point classification. Pass NULL for the point style to reset the default drawing style to the default style for that classification of point.

Typically, when modifying the drawing style of a point class you'll want to call GM_GetPointFeatureClassDrawStyle to get the current drawing style, then just change what you need, then pass your copy in to this function.
