The Throrium browser and Throrium browserW7 author did make a chromium 49 fork
– Codecs, Widevine, and Google Sync (Widevine wont work though)
– Compiler optimizations (see SSE3 note down below)
– Fixed building with Visual Studio 2015 and the 10586 WinSDK
– Re-enabled hardware acceleration (and things like WebGL!), via SwiftShader
– Backported a few M54 patches
– Added some patches from Thorium
