This patch fixes a case of framebuffer blitting with renderbuffer as color attachment and GL_LINEAR filter. Meta implementation of glBlitFrambuffer() converts source color buffer to a texture and uses it to do the scaled blitting in to destination buffer. Using the exact source rectangle to create the texture does incorrect linear filtering along the edges. This patch makes the changes to extend the texture edges by one pixel in x, y directions. This ensures correct linear filtering. It fixes failing piglit fbo-attachments-blit-scaled-linear test.
