FS#11820 - iPod Colour LCD: artefacts left onscreen at shutdown.


iPod Colour shows horrible artefacts left on the screen for quite some time after shut-down.
More often than not in the form of a pair of jagged vertical lines in the approximate centre of the screen, spaced 1~2px apart.
Looking rather similar to a lightning strike.
Very occasionally (1 in 50 or so) a piece of the theme or statusbar is “left behind” in the same or similar way on shut-down and fades out very slowly over a period of minutes.
It happens on both manual and idle time-out shut-down, but seems to present more reliably when the device is shut-down manually.
This is present for me on two different devices (iPod Colour 64GB CF and iPod Colour 60GB HDD)
I have also tried the 3.7 and 3.7.1 release builds and the problem is present there also.

Fixed with r29033

This patch takes the lcd_type identification and shutdown code from FS#10034.

Positively tested on iPod color (lcd_type 3) by Hayden Pearce.

v04 fixes white flashes of the display when entering sleep mode or when shutting down.

Positively tested on iPod color (lcd_type 3) and nano1g (lcd_type 1) by Hayden Pearce. No lcd_type 2 available for testing yet.
