I’ve been trying really hard to draw a GL_TEXTURE_RECTANGLE_ARB to a GL_TEXTURE_2D in order to perform mipmapping, which GL_TEXTURE_RECTANGLE_ARB does not support.

I’ve tried accessing the pixel data directly but with no success. If you should succeed with accessing the pixels, please post your solution.
