I tried to test the software backend drawing in MiniBrowser using the -e=software_x11 option.
If you got the error when using the MiniBrowser on software backend, please leave the comment here.

I installed libosmesa6-dev manually and then rebuilt jhbuild 
modules and WebKit too, but still get crash immediately:

$ WebKitBuild/Release/bin/MiniBrowser -e=software_x11
Segmentation fault (core dumped)

When I do same thing on Ubuntu 15.10, MiniBrowser works well. I wonder if Ossy still has the problem.

When I installed libosmesa6-dev, I don't have any problem locally yet. Do you have problem ?

[Gyuyoung Kim]

I verify that "-e=software_x11" option works well. When I run the CanvasMark benchmark. There is big performance gain between on/off the option.

CanbasMark benchmark- http://www.kevs3d.co.uk/dev/canvasmark/

The result is as below,

 - CanvasMark Score: 13896 (EFL MiniBrowser with software_x11)
 - CanvasMark Score: 6149 (EFL MiniBrowser without software_x11)
 - CanvasMark Score: 7067 (Chrome 49 on Linux)
 - CanvasMark Score: 11244 (Firefox 47 on Linux)

(All tests were done by same PC)

EFL MiniBrowser score is better than Chrome and Firefox. :)
