-See {{bug|430829}}, [[Gfx_glue_layer_removal]] and [http://groups.google.com/group/mozilla.dev.tech.gfx/browse_thread/thread/90d41db79b03f2fb/8921df6eaa49269c?#8921df6eaa49269c the thread on mozilla.dev.tech.gfx].
+An important step for MathML is {{bug|663740}}, which will allow to start the work on OpenType MATH table, to support more [[MathML:Fonts|MathML fonts]]. More generally, see {{bug|430829}}, [[Gfx_glue_layer_removal]] and [http://groups.google.com/group/mozilla.dev.tech.gfx/browse_thread/thread/90d41db79b03f2fb/8921df6eaa49269c?#8921df6eaa49269c the thread on mozilla.dev.tech.gfx].
-We should rewrite the MathML layout engine to remove nsIRenderingContext, use gfxFont::Metrics instead of nsBoundingMetrics etc
-== Attribute mapping into style ==
-We are using private attributes and pre-defined rules in mathml.css to map some MathML attributes into CSS. This approach shows its limits for length attributes {{bug|330964}} and exposes unwanted attributes to the DOM {{bug|527201}}. We should rewrite this in a cleaner way {{bug|69409}}.

-== Box model for MathML ==
+Our layout engine still has some problems with width computation. See for example {{bug|459363}} or {{bug|415413}}. Should we find a better algorithm?
-The <math/> element is implemented as an inline-box, but this gives an incorrect height computation {{bug|219873}}. We should also allow linebreaking inside <mrow/>'s, as specified by the rules of MathML 3 {{bug|508120}}.
