With the new lcd_putsxy_scroll_func() code can register custom scroll functions
(put_line() makes use of that). In order for the custom scroller to be able
to properly manage its userdata pointer (set via struct scrollinfo::userdata)
the scroll engine must inform the scroller about start and stop of scrolling.
To inform about start the lcd_scroll_* functions now return true when
the line will scroll. To inform about stop the scroll engine calls into the
scroller one last time, with the text set to NULL.
put_line() can use this to release the userdata registered per scrolling line
so that it can be recycled.
This fixes that some scrolling lines became glitchy after some time because
the userdata was recycled too early.

usb_storage needs a fairly reasonable amount of memory. Allocating
what we need and no more allows other (future) USB drivers to get
something too, and is much cleaner in general.

This is used by lcd_puts_scroll_worker() to render the line immediately
instead of waiting for the next scroll tick when only the text was updated.
Previously lcd_puts_scroll_worker() did not render anything in this case
which could lead to visible blinking.
This fixes blinking scrolling lines with dynamic text in the skin engine.

The code expected the color table at offset 54 (14+size of BITMAPINFOHEADER),
which was after the BITMAPINFOHEADER header. However, newer BITMAPINFOHEADER
versions exist which have more fields before the color table. Fix this by
explicitely seeking to the color table.

If logf is enabled, panic() will print the last lines. On small
screens this is more or less useless, but on large screens it
can be very useful for debugging.

This was lost in 97a4c1ef (svn r30177) for unkown reason but the manual still
mentions this item, so I assume it was an accident. It doesn't hurt anyway.
Fixes FS#12930.

The %Vf and %Vb tags change the colors for the rest of the viewport. This
requires the rest of the vp to be redrawn when they change due to a conditional.
The previous code did this redraw in all cases (conditional or not) which
led to visible blinking.

Because inline strings have to be copied (to escape '$') the local buffer
can be exhaused. The code didn't check for this. The buffer is increased
to handle filenames plus some extra chars but truncates to avoid overflow.
If you have longer strings please pass them via $t tag, in which case
put_line() imposes no additional length-limitation.

put_line() needs to change fore- and background colors if required by
the line style. This should really only be done if required, and be undone
as to not compromise subsequent lines. This fixes %Vf and %Vb skin tags.

1) The 9-segment images need not be multiple of 3 pixels anymore. If it
isn't the inner segments will be smaller than the corners.
2) If the desired actual images is not a multiple of the segment sizes the
function drawed more than the desired rectangle. This is fixed by
drawing the last segment only partially.

This simple program shows how to setup timer for periodic
operation. Interrupts are not used yet and simply pending
irq bit is polled and cleared when set. This program
supports my understanding of disassm of ADEC_N63.BIN that
P_CLK is configured for 7.5MHz and timer clock source is P_CLK
directly.

Greylib performed a horrible hack and stored fg and bg patterns in other
struct viewport fields. One of them was just removed. So instead of
this hack simply enable the *_pattern fields for mono targets as well,
so that greylib can use them normally.

These where used for line styling during scrolling, which is now done in apps/,

This logic is moved into apps (put_line()) which can better handle line
decorations with respect to scrolling, mulitline and other complications.
Firmware doesn't need this. The remaining drawing function know only one style,
that is foreground on background/backdrop (changing drawmode is still supported).

This main (and only) purpose for it was to adjust the pixel position of the text

this isnt necessary anymore.

Since scrolling is now pixel-based this is not necessary anymore. custom line

With this functions removed there is no exported function in firmware left
that draws line decorations. Also no function supports specifying an y-offset
anymore (was used for pixel accurate positioning of otherwise strictly line-based
API calls).
Both should be handled in apps/ now.

This function is a fully-fletched, high-level pixel-based line printer, that
combines functionality of several firmware and list functions. It can
draw spacing, icons and text in a single call, in any order and each multiple
times. It can also apply line decorations at the same time.
It features printf-like semantics by accepting a format string that contain
format tags as well as inline text.
It's accessible directly, but also through the multi-screen api for plugins.

Since x is viewport-relative the icon isn't necessarily placed at the physical
display boundaries so that the padding isn't always useful. In fact it does
more harm if one wants to place an icon exactly at 0 of a (non-default)
viewport.
Calling code looks still mostly fine. I've only modified list drawer to include
the padding in the call-site.

This function supports installing a custom scroll callback. This will be
called when the scrollengine redraws the line. It allows to draw extended
styles (or anything your can possible imagine) along with the text.
It is also strictly pixel-based, the first pixel-based function that supports
scrolling.
