So, should I put PT first and have the following order?

+typedef enum _cairo_svg_unit {
+    CAIRO_SVG_UNIT_PT = 0,
+    CAIRO_SVG_UNIT_EM,
+    CAIRO_SVG_UNIT_EX,
+    CAIRO_SVG_UNIT_PX,
+    CAIRO_SVG_UNIT_IN,
+    CAIRO_SVG_UNIT_CM,
+    CAIRO_SVG_UNIT_MM,
+    CAIRO_SVG_UNIT_PC,
+    CAIRO_SVG_UNIT_PERCENT,
+    CAIRO_SVG_UNIT_USER
+} cairo_svg_unit_t;

Or can I stick to the "official" order suggested by the specification
[1], and just mention in the API doc that "pt" happens to be the default
unit for *cairo*, if cairo_svg_surface_set_document_unit () is not
called?

Thanks,
   Antonio

A: Because it messes up the order in which people normally read text.
