[sldev] Fatal error when running SL client 1.20

[Ying Zhong]

Hi guys,

I downloaded  Branch_1-20-Viewer-2-r90824 and had it compiled 
successfully. But when I try to run it under "ReleaseNoOpt" there is an 
fatal error says:

ERROR:LLImageGL::createGLTexture failed to make texture

There was one email talked about this error before but there was no 
solutions for this error. So, would anyone give me some suggestions? I 
will be appreciated for that very much!

Best Regards,
Ying
