Fix FS#12981 JPEG decoding problem when entropy data starts with FF

2016-04-01T17:29:41+00:00

This changes JPEG fill and invalid byte handling to be like
mozjpeg, and bases entropy data start on SOS marker location.

Thanks to Stefan Waldmann and Dean Tersigni for reporting.

lcd-24bit: Introduce a 24-bit mid-level LCD driver

2014-06-20T22:15:53+00:00

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).

imageviewer: gif viewer based on giflib-5.0.2

2012-11-13T17:13:10+00:00

This adds ability to view gif images in rockbox.
Works both on color and gray/monochrome targets (greylib).
Aspect correction is supported as well.

Limitations:
- animated gifs are restricted to 32 frames
- animated gifs loop always (loopcount is ignored)
- plain text extension is not supported
- animated gifs with interframe delay = 0 are treated as still
  images (web browsers usually treat delay 0 as 100ms to prevent
  exhaustive CPU load by such images)

FS#10535: bmp viewer plugin.

2010-02-18T15:10:31+00:00

* changed bmp.c so that it loads bitmap larger than LCD correctly.
* removed bmp entry form inbuilt_filetypes in filetypes.c so that bmp files will be opened with bmp viewer when selected in browser.
