[Piglit] [PATCH] framework: specify GL_NEAREST filter for FBO textures

[Brian Paul]

By setting the min/mag filters, we give a hint to the OpenGL driver
that we probaby don't want mipmapped textures.  This results in the
Mesa state tracker allocating single-level textures here instead of
full mipmaps.
