I designed the current SVG Filters implementation in a way that hopefully make 
it possible to implement HW accelerated filters on top of it. Skia and NEON 
already go this path. I am not defending the OpenCL implementation for SVG 
Filters per se, but different platform dependent solutions were expected and 
wanted. Software filters were designed to be a fallback if an implementation 
does not provide HW acceleration (yet). I hope that we see a Core Image version 
of filters in the near future as well. The code for that is in the history of 
the repository already.

Re: [webkit-dev] WebKit + OpenCL

[Andreas Kling]

Hi folks,

Do we really think it's a good idea to add yet another implementation of 
filters?

We already have generic, NEON-optimized and WTF::ParallelJobs (which includes 
generic, OpenMP and libdispatch backends) implementations of this code, and now 
we're adding OpenCL too.

On the WebKit Project Goals page , 
it states that:

"WebKit is an engineering project not a science project. For new features to be 
adopted into WebKit, we strongly prefer for the technology or at least the use 
case for it to be proven."

Correct me if I'm wrong, but we don't see much use of these features on the 
web. I understand that there's a bit of a chicken/egg problem where a feature 
won't be interesting to content creators until it performs well enough, but it 
seems like we could at least decide on a single path forward instead of 
repeatedly forking the code.

Re: [webkit-dev] WinLauncher Fail to launch

Depending  on how long ago he pulled (i think this was fixed in later
revisions), you may need to do the following:


In /Tools/win/DllLaunchermain.cpp Comment out:

//if (!modifyPath(programName))

// return 1;
To not check for apple products.

Hi Rakesh,

If you build the WinCairo port, you don't need iTunes or Safari to be installed.

Hi Rakesh,
The WinCairo port only has a partially functional WebKit2 port. Consequently, 
MiniBrowser does not launch.
You must run the WinLauncherLauncher target to see a working program. The 
WinLauncher project builds a DLL that holds the a trial program logic, but does 
not run as an executable.  This came about during the start if the WebKit2 work 
(WK2 runs as an external process to the main program executable, hence the new 
*LauncherLauncher projects.)
