 #### 3. Dual source subpixel blending in OpenGL
 
 The third approach is similar to the second approach, but makes use of the [`ARB_blend_func_extended`](https://www.khronos.org/registry/OpenGL/extensions/ARB/ARB_blend_func_extended.txt) extension
 in order to fold the two passes into one:
 Instead of outputting the two different colors in two separate passes, we output them from the same pass,
 as two separate fragment shader outputs.
 Those outputs can then be treated as two different sources in the blend equation.
 
-This method of text blending has not been implemented in WebRender yet.

 ## Subpixel Text Rendering to Transparent Destinations with a Background Color Hint
 
 ### Motivation
 
 As we've seen in the previous section, subpixel text drawing has the limitation that it only works on opaque destinations.
 
 In other words, if you use the `subpixeltextblend` function to draw something to a transparent surface,
 and then composite that surface onto on opaque background,
