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).

Fractals: Remove redundant assignment to a variable (y_delta)

Also some cosmetics

mandelbrot: start with bright colors on greyscale

mandelbrot: use correct colors on greyscale targets (FS#10935)

2010-01-30T07:16:16+00:00

Tested on Clipv1 (sim/target) and Ipod3g (sim)
Each color would be calculated as 0

Note the iteration over the whole range of colors is quite weird, and I
can not really sense what max_iter represents (except it's a number of
different colors, right?)

It should be backported to branch after tomers check if color range is
correct (FS#10935 mentions much smaller range for color targets as well)

Fractals: this should fix bugs on simulator for greyscale LCD targets.

2010-01-21T12:27:07+00:00

* moved #define USEGSLIB to fractal_sets.h and include only needed header file.
* include plugin.h so that LCD_DEPTH is defined.
* explicitly include fractal_sets.h in mandelbrot_set.c

Fractals: Prevent zooming more than deepest possible zoom

This prevent the mandelbrost set from being trashed if zooming too much
