The code that should provide reasonable defaults, but doesn't for some reason:
It's scaling the BP by 128 for some reason, between the time it's created and the
time we get back to the SI widgets:

static void OnBtnAxial(GtkWidget *widget, gpointer data)

  Select_SetTexdef(projection);

Select_SetTexdef() calls Scene_BrushSetTexdef_Component_Selected(GlobalSceneGraph(), projection)

Texdef_Assign(m_texdef, texdef, m_brushprimit_texdef, brushprimit_texdef) in class Face...
which just copies from brushpr to m_brushpr...
