test chart with sierrachart

When using Wine 11 with Sierrachart and opening any chart with OpenGL enabled,
the screen is blank.  Wine 10 worked without any OpenGL issues.  

A workaround is to turn OpenGL off in Sierrachat, restart Sierrachart and
graphics work.

From SC support

@ertrader: Wine 11 uses the EGL backend by default for OpenGL, which may be
incompatible with some older hardware.

I was able to get OpenGL to to work with an older Nvidia card by forcing the
GLX backend:

Open the registry editor (on the terminal):
wine regedit

Go to the following Key:

HKEY_CURRENT_USER\Software\Wine\X11 Driver

Add a string value:

UseEGL

Set it to:

N


And then start Sierra Chart, and you should be able to see the chart while
using OpenGL, just like they worked in previous versions of Wine. 
----------------------------

This workaround worked.
