commit a0b361e58098a446de60b2e911587f9076bd1f25
Author: estade <estade@chromium.org>

Get rid of some lingering MD-specific raster assets.

Part of this is deleting obsolete bookmark action bar chevron code on Views.

Only pdf.png remains (on Views at least) and I've pinged sgabriel/bettes
for a replacement.
