Returns the maximum number of triangles. Just so we can allocate enough before instancing. This does not take into account degerate triangles or ADC b

This is manually inlined in CalcTextSizeA() and CalcWordWrapPosition(), with a non-inline call to BuildLoadGlyphGetAdvanceOrFallback().

References are only valid until a new value is added to the storage. Calling a Set***() function or a Get***Ref() function invalidates the pointer.

FIXME-OPT: Need a way to reuse the result of lower_bound when doing GetInt()/SetInt() - not too bad because it only happens on explicit interaction (m
