Subject: [PATCH] Redraw brightness slider on density change.

Without this, the drawable we use for the brightness slider gets
drawn at the wrong size whenever the screen density changes. This
also appears to ensure that the brightness icon gets drawn in the
correct color.

Fixes: 191738397
Test: manual
