The perceived loudness change of a change in volume depends
on the listening volume: at high volumes a 1 dB increment is
noticeable, but at low volumes a larger increment is needed
to get a comparable change in loudness.
Perceptual volume adjustment accounts for this fact, and
divides the hardware volume range into a number of steps.
Each step changes the dB volume by a variable amount, with
most of the steps concentrated at higher volumes. This
makes it possible to sweep over the entire hardware volume
range quickly, without losing the ability to finely adjust
the volume at normal listening levels.
Use "Volume Adjustment Mode" in the system settings menu
to select perceptual volume mode. The number of steps used
is controlled by "Number of Volume Steps". (Number of steps
has no effect in direct adjustment mode.)
It's still possible to set a specific dB volume level from
the sound settings menu when perceptual volume is enabled,
and perceptual volume does not affect the volume displayed
by themes.

Since synclists are now re-initialized after leaving
Settings menus where the callback was used, it
shouldn't be needed anymore.
gui_synclist_init_display_settings can also be made
local to list.c now.

Only the "Rockbox Info" screen uses it for a rather silly purpose,

Removing the "list_wrap" argument is actually pretty easy.
In practice, almost all lists are using LIST_WRAP_UNLESS_HELD
behavior so we can make that the default. A couple of lists
disable wraparound with LIST_WRAP_OFF; this is now achieved
by setting the list "wraparound" flag to false when setting
up the list. LIST_WRAP_ON was unused and is of questionable
value, so it has been removed entirely.
This makes list wraparound behavior a property of the list,
controlled solely by the "wraparound" flag. The result is a
simpler list API and implementation, without changing the
behavior of any lists.

Since gui_synclist_do_button() overrides the setting at runtime
there is no reason to have a public API call to set it. Really
it should be a local variable, but it will be simpler to do that
after refactoring how list wraparound behavior is handled.

gui_list_screen_scroll_step() and gui_list_screen_scroll_out_of_view()
just copy the global setting into a local static variable.
Since they don't do anything special when the setting changes
it's simpler to use the global setting directly.

The implementation of the "show_selection_marker" option in
lists isn't great. It's a cosmetic option used to hide the
selection, but it causes the list to do funny things to the
selected_item and doesn't play nice with voiced menus, since
these rely on the selection to determine what item is spoken.
There are only two user-facing lists that use the option, the
"Rockbox Info" screen and a menu in the superdom plugin. The
rest are debug screens, and cosmetics don't matter much there.
Given how little used the option is, and its issues, removing
it seems reasonable.

Use const char* pointers for list titles. Only one debug menu
actually modifies the title, and in that case it's legal to
cast away const because the title points to a known mutable
buffer on the stack.

its really painful needing to override global settings in order to change
some aspects of lists
this patch moves:
[scrollbar position, cursor type,
talk_menus, keyclick,
wrap around, scroll paginated]
to variables within the synclist, it also makes updating
after settings changes a necessity
I think I have the static synclists in core covered
(I think the one in gui/list-skinned can be left as is)
this patch allows easy modification these flags on the fly

allow the guts of gui_sync_list to be used with owner drawn items
WIP
printcell_helper--
goal: allow data to be displayed in a spreadsheet format with an easy to use interface
printcell_set_columns(gui_synclist, title, icon)
sets title and calculates cell widths
each column is identified by '$' character
ex 3 columns title = "Col1$Col2$Col3"
also accepts $*WIDTH$
ex 3 columns varying width title = "$*64$Col1$*128$Col2$Col3
printcell_enable(gui_synclist, enable)
sets the printcell function enabled
After setting the columns and enabling the printcell function
items can be added to the list like normal
column items are supplied delimited by '$'
ex item = "Item1$item2$item3"
they will be placed in cells defined by set_columns and scroll if the cell is too small

AUDIOHW_SETTING() defines number of decimals and step size.
This is taken into account in sound menu but ignored in lists
(had been recently fixed in WPS).
This was not a problem so far since all drivers used 0 decimal
places and step size equal 1.

Depending on the actual keymap, canceling a listtree with the
"scroll left" button may not be intended, especially
if the list is entered from a completely different focus
(think of leaving a plugin with "long left")
Note:
initializing "scrolling_left" with true without anything actually
scrolling sounds odd to me... maybe this variable should be renamed?
"pgleft_allow_cancel" comes to my mind (with opposite boolean states)

add_event_ex is added that takes an extra user_data pointer. This pointer is
passed to the callback (add_event and add_event_ex have slightly different
callbacks types). All callbacks also get the event id passed. Events added
with add_event_ex must be removed with remove_event_ex because the user_data
pointer must match in addition to the callback pointer.
On the other add_event is simplified to omit the oneshort parameter which
was almost always false (still there with add_event_ex).
As a side effect the ata_idle_notify callbacks are changed as well, they
do not take a data parameter anymore which was always NULL anyway.
This commit also adds some documentation to events.h

This is a bit of a hack. We now trigger an event when the skin engine
is doing a full redraw (which means fullscreen clear) before the
lcd_update() to give the current screen a chance to redraw to avoid the
screen flicker.
This commit fixes the issue for screens which are entirely the list
widget (i.e browser and menus), other screens will need aditional fixes
(i.e quickscreen, time&date screen)

The time&date screen uses a custom parent for do_menu(), and doesn't
account for the buttonbar and list line height. Introduce
gui_synclist_set_viewport_defaults() to set those for viewports that are
going to be list parents and use that so that time&date screen doesn't need
to know about buttonbar/line padding.

This adds line padding to lists on touchscreens,
in order to make lists reasonably useful without huge fonts.
It's configurable:
* Automatic (default, line height calculated using a lcd dpi aware function)
* Off (status quo, line height = font height)
* X pixels (from 2 to 50 in even steps)

due to lack of user feedback the actual tags may change, hopefully not though.
The way it works is the skin specifies a rectangle and a viewport label. For each item in the list that is being displayed all viewports with the specified label are drawn. However, instead of the viewport x/y position being offset from the top left corner like normal they are offset from the rectangle position in the list (so think of them as child-viewports of the rectangle which moves).
Normally the rectangle will move down the screen to show a normal list, this can be changed to move across the screen in a grid pattern.
The UI viewport is used to bound the items (i.e %Vi() )
Scrolling is completly disabled in all items except the currently selected item.
This works well in combination with the %cs tag to show differently styled lists based on the current screen :)
New tags:
%LT - Get the current items text
%LI - Get the current items icon number
%Lc - Use as a conditional to determine if the current item is the selected item
%LB - BAR TAG to show the scroll bar, params/options like other bar types. It still needs a bit of work though. Use as a conditional to find out if the bar is actually needed
%Lb(viewport, width, height [,tile]) - specify the viewport label to draw for each item and the size of each item. if the last param is 'tile' it will form a grid instead of a list
example.sbs:
%?cs<%Lb(a,100,20)|>
%V(0,0,10,-,1)%Vf(aabbcc)
%?LB<%LB(0,0,10,185, invert)>
%Vi(-,10,0,-,-35,1)
%Vl(a,5,5,160,12,1)

This adds kinetic scrolling to to lists on touchscreen targets and RaaA, like all other OSes on touchscreens have.
It's only enabled in the absolute point mode, so for non-touchscreen and in grid mode nothing changes.
Kinetic scrolling means that the list keeps scrolling (but is decelerating) after you leave the touchscreen with the finger.
Redraw interval and deceleration is hardcoded for now but could be made configurable if desired.
