io_tinycad 
 Limitations and knonw bugs 
	-  no support for arcs in polygon (susbtituted with straight lines)
	
-  the implicit titleblock is not imported
	
-  slot is kept in tinycad's slot concept, not converted to sch-rnd's slotting; netlist export should be fine, but changing slot on an existing symbol is not easily possible
	
-  ellipse objects are line-approximated
	
-  [TYC#1] multiline text in note is not supported yet - requires multiline text support in libcschem (planned)
	
-  [TYC#3] no support for hatched polygons (they are loaded as filled)
	
-  [TYC#4] no support for hatched rectangles (they are loaded as filled)
	
-  [TYC#6]  is ignored; this is the sheet's visual name printed in the GUI tab in tinycad (sch-rnd always uses the file name)
