* lcd-24bit: Introduce a 24-bit mid-level LCD driverThomas Martitz2014-06-21
| | | | | | | | | | | | | | | | | 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-5.0.2Marcin Bukat2012-11-13
| | | | | | | | | | | | | | | | 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) Change-Id: I61501f801ddcd403410e38d83e6bddc9883e7ede
