nsISVGGlyphMetricsSource Interface

 \addtogroup rendering_backend_interfaces Rendering Backend Interfaces
 @{


 Abstracts a description of a 'composite glyph' (character string
 with associated font and styling information) in the SVG rendering
 backend for use by a rendering engine's nsISVGRendererGlyphMetrics
 objects.

 An engine-native glyph metrics object will be informed of changes
 in its associated composite glyph with a call to its
 nsISVGRendererGlyphMetrics::update() method with an OR-ed
 combination of the UPDATEMASK_* constants defined in this interface
 (and its base-interface).
