several issues I saw that could pontentially cause problems
scroll engine doesn't take text height into account when checking bounds
NBELEMS was one whole row too large hopefully I got them right this time

I'm currently running up against the limitations of the lcd_draw functions
I want these functions to be able to be used on any size buffer not
just buffers with a stride matching the underlying device
[DONE] allow the framebuffer to be decoupled from the device framebuffer
[DONE need examples] allow for some simple blit like transformations
[DONE] remove the device framebuffer from the plugin api
[DONE}ditto remote framebuffer
[DONE] remove _viewport_get_framebuffer you can call struct *vp = lcd_set_viewport(NULL) and vp->buffer->fb_ptr
while remote lcds may compile (and work in the sim) its not been tested on targets
[FIXED] backdrops need work to be screen agnostic
[FIXED] screen statusbar is not being combined into the main viewport correctly yet
[FIXED] screen elements are displayed incorrectly after switch to void*
[FIXED] core didn't restore proper viewport on splash etc.
[NEEDS TESTING] remote lcd garbled data
[FIXED] osd lib garbled screen on bmp_part
[FIXED] grey_set_vp needs to return old viewport like lcd_set_viewport
[FIXED] Viewport update now handles viewports with differing buffers/strides by copying to the main buffer
[FIXED] splash on top of WPS leaves old framebuffer data (doesn't redraw)
[UPDATE] refined this a bit more to have clear_viewport set the clean bit and have skin_render do its own screen clear
scrolling viewports no longer trigger wps refresh
also fixed a bug where guisyncyesno was displaying and then disappearing
[ADDED!] New LCD macros that allow you to create properly size frame buffers in you desired size without wasting bytes
(LCD_ and LCD_REMOTE_)
LCD_STRIDE(w, h) same as STRIDE_MAIN
LCD_FBSTRIDE(w, h) returns target specific stride for a buffer W x H
LCD_NBELEMS(w, h) returns the number of fb_data sized elemenst needed for a buffer W x H
LCD_NATIVE_STRIDE(s) conversion between rockbox native vertical and lcd native stride (2bitH)
test_viewports.c has an example of usage
[FIXED!!] 2bit targets don't respect non-native strides
[FIXED] Few define snags

Note: I left behind lcd_bitmap in features.txt, because removing it
would require considerable work in the manual and the translations.

HAVE_LCD_BITMAP is now redundant.
lcd_bitmap is always-on in features.txt so manual and lang strings
don't have to change

With LCD driver all calculation will be performed on RGB888 and the hardware/OS
can display from our 24bit framebuffer.
It is not yet as performance optimized as the existing drivers but should be
good enough.The vast number of small changes is due to the fact that
fb_data can be a struct type now, while most of the code expected a scalar type.
lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit
it enforces the generic C code.
All plugins are ported over. Except for rockpaint. It uses so much memory that
it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

This patch adds a configurable line separator between list items, very
similar to lists in Android. Additionally, below the list item there is a
thicker line. It can be disabled in the settings. Its color can
be configured as well.
Remote and monochrome displays are explicitly unsupported. If there is desire
this can be changed but it doesn't seem useful to me.

DPI values are autogenerated from the resolution and collected display size
values. These values are inserted as comments as well.

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.

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.
Change-Id: Ib0842ebcc97f5bf9d9382b4471903afa2f96f39f
These where used for line styling during scrolling, which is now done in apps/,
The viewport struct doesn't need to record these anymore.
Change-Id: I810d9dcb2644b00a798c6e75acab69c74a78e77f
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).
Change-Id: I707060edc388a7d723a7d09b0cf5cbda6ec56708
Since scrolling is now pixel-based this is not necessary anymore. custom line
height is handled by put_line() but can also possible to implement with
lcd_puts_scroll_func().
Change-Id: Iee9b12bf99afac93d95d2a1a6f5d5b4db237b21c
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.

It is similar to lcd_gradient_fillrect(), except that it only draws a part
of the complete gradient. This can be used to draw only the bottom half
of a full gradient.

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.

Some seldomly used drawmode combinations did not work in conjunction with
alpha bitmaps and backdrops. Now all should work (see comment added) by using
more bits.

This allows to draw lines without destroying styles that were drawn manually
(e.g. from apps/) beforehand.

Use %x9(id) to draw an image in the whole current viewport using the
9 segment drawer (which draws the corners as normal and *tiles*
the middle segments to the needed width/height).
Future work is to make it scale instead of tile

lcd_gradient_rect() was only usable to draw list lines, so split
it up and make a generic gradient draw function available to apps/

The framebuffer the lcd driver uses can now be changed on the fly
which means that regular lcd_* drawing functions can draw onto the
"backdrop" buffer. The skin engine can use this to create layered
effects.
Add the tag %VB to a viewport to draw that viewport onto the
backdrop layer. If you want to draw an image onto the backdrop
framebuffer use %x(backdrop filename) instead of %X() inside
a viewport with %VB.
Change-Id: I741498e2af6d4f2d78932cabe8942317893e7cfc
Change all lcd drivers to using a pointer to the static framebuffer
instead of directly accessing the static array. This will let us
later do fun things like dynamic framebuffer sizes (RaaA) or
ability to use different buffers for different layers (dynamic
skin backdrops!)

Massage the way it interfaces a bit to make things more flexible.
The chroma_buf scheme on Sansa Connect and Creative ZVx calling the
lcd_write_yuv420_lines implementation in lcd-as-memframe.S with five params
with a chroma buffer that the function can't use wouldn't work anyway so just
have them use the stock implementation (really, how was that working?).

This uses the alpha blending capabilities introduced with anti-aliased fonts
to draw bitmaps with transparency information. The bmp loader is extended to read
this information (pass FORMAT_TRANSPARENT in format). The alpha information will
be used when drawing the bitmap.

This new APIs wrap around lcd_[mono|transparent]_bitmap/_part calls and
handle all kinds bitmaps. The intended use is to draw bitmaps that
come from read_bmp_fd/_file.

- Bump plugin ABI for the changed viewport struct (sort the API too).

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)
The automatic setting should/aims to Just Work Out Of The Box on all targets

Remove the hardcoded (and way too small) scroll threshold (the distance moved in pixels before we think the users wants to scroll) and replace it with something based on the actual DPI of the screen.
On Android we call the API for that, on other touchscreens we reimplemented Android's formula (as of 2.2) and calculate it.

The parameter wasn't used yet and it's not clear whether it should be a absolute or relative viewport.

They work as the drawrect/fillrect pendants but work on a viewport basis; pass NULL to draw the current viewport (the one set with set_viewport()).
In conjunction with action_get_touchscreen_press_in_vp() it should be less of a pain to draw buttons and get presses on them.

Looks much smoother now as you don't scroll by whole lines anymore.
Add some functions lcd driver to enable the line based scrolling engine to draw the lines with a pixel-based y-offset.
This should also allow for a sensible kinetic scrolling mechanism (still a todo).

Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back.
Only implemented for PP and as3525 so far. More targets could be added, as well as more functions.
