As per OpenGL 3.0 specification section 3.9, page 187 in pdf the maximum allowable width, height, or depth of a texel array must be at least 2^(k−lod) + 2*bt for image arrays of level-of-detail (lod) 0 through k, where k is the log base 2 of MAX_3D_TEXTURE_SIZE, and bt is the maximum border width
Currently different values for maximum allowable texture size are returned by glGetIntegrv() and proxy textures. glGetIntegrv returns 2048 and proxy texture returns (2048 + 2) This patch fixes Intel oglconform test case: max_values Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=44970 Note: This is a candidate for mesa 8.0 branch.
