#699 Texture filter won't apply

[Sam Al-Awami]

In OpenGL mode, if I change texture filtering to "Nearest" it would initially work fine, but upon restarting Doom Legacy the filter won't take effect and must be "refreshed" even though the option label is showing "Nearest" as you can see in the attached screenshot.

Sorry, the system did not notify me of this bug report, so I have just discovered it.
Confirmed, that the OpenGL setup does not update from saved opengl config settings.
This whole area of the code needs review.
