The frame's quiet bodyguard, keeping art from kissing glass and fogging up.

means A border or sheet of material placed between artwork and its frame (or glass) to protect the piece and set it off visually.

from From 'mat/matte,' tracing back through French 'natte' to Latin 'matta,' meaning a woven rush mat or coarse covering — the same root that gives us floor mats. The woven-floor-covering sense came first; the framing sense borrowed the word because the flat board surrounding a picture resembled a mat laid down around something precious.
