Subject: Use texture->first_level, not 0, when not mipmapping.
X-Git-Tag: 062012170305~17580^2~390^2~3988
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f14ece2d2c9add5ebf21171746f34ce60ff0df3b;p=profile%2Fivi%2Fmesa.git

Use texture->first_level, not 0, when not mipmapping.

Fixes crash when GL_BASE_LEVEL!=0.
Also, remove old assertion.
