This, for example, is for an LDPI device:
BOARD_RECOVERY_FONT_INCLUDE_HEADER := ../../device/geeksphone/one/font_7x16.h
BOARD_RECOVERY_FONT_WIDTH := 7
BOARD_RECOVERY_FONT_HEIGHT := 16

Make ui_init() clear the framebuffer memory it maps in so the user
isn't treated to a visible flash of random bits on recovery startup.
Call ui_set_background() (to show the installing icon) right after
ui_init() to display something while device_recovery_start() is
working (which can take a second or two on some devices).
