Created attachment 120014 [details] Patch V1 The spec seems to have been updated to use 1 by 1 as the default mesh. I've also updated that and added some comments.
Created attachment 120018 [details] Patch V2 Using the StringBuilder only inside the CachedShader.cpp file.
Comment on attachment 120018 [details] Patch V2 View in context: https://bugs.webkit.org/attachment.cgi?id=120018&action=review Much nicer, thanks a lot. r=me with a few comments: > Source/WebCore/platform/graphics/filters/CustomFilterShader.cpp:51 > +const char* CustomFilterShader::defaultFragmentShaderString = > + "precision mediump float;\n" \ I admit, I like the other solution much more now :-) It's much more readable, would you mind updating it once again? > Source/WebCore/platform/graphics/filters/CustomFilterShader.h:79 > + static const char* defaultVertexShaderString; > + static const char* defaultFragmentShaderString; This could be removed again using this SHADER technique.
Landed in r103535. Closing the bug.
