Add two new line selector types: solid colour and gradient. Solid colour only uses the primary colour setting. The secondary colour setting is used for the gradient. Text colour for the selected item is also changeable. These new settings are a bit controversial so they may be removed later. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14868 a1c6a512-1295-4272-9138-f99709370657

*
|
|
* A bitmap contains one bit for every pixel that defines if that pixel is
|
|
* black (1) or white (0). Bits within a byte are arranged vertically, LSB
|
|
* at top.
|
|
* The bytes are stored in row-major order, with byte 0 being top left,
|
|
* byte 1 2nd from left etc. The first row of bytes defines pixel rows
|
|
* 0..7, the second row defines pixel row 8..15 etc.
|
|
*
|
|
* This is the mono bitmap format used on all other targets so far; the

* pixel packing doesn't really matter on a 8bit+ target. */
