* 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).

* Latest work on the bmp on-load scaler:Andrew Mahone2008-12-26
| | | | | | | | | | | | | | | | | | | | | | | | | Macros for calculating size needed for bitmap load and scaling, so that these can be compile-time constant when their inputs are. Reduce size of bayer dither by chopping all but first row of dither matrix, and replacing 2D lookup with 1D lookup and small calculation. Move some functions not related to actual bmp file loading out of bmp.c. A smaller brightness() for mono targets, and a higher-quality one for greyscale targets, both replacing the division by 10 with a shift. Port of the linear and area scalers to greyscale targets, this costs some binsize but produces better output even when dithered to 2bpp. Move duplicated row output code from inside vertical scalers to a separate row output function. Move some multiplies out of the line scaler, for a small speedup and code size reduction, as well as a small improvement in accuracy for the upscaling case. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19592 a1c6a512-1295-4272-9138-f99709370657
