lcd/grey: Enable viewport fg_pattern and bg_pattern for all bitmap targets.

2014-01-07T21:14:41+00:00

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.

Adapt OSD in plugin lib to be greylib compatible.

2012-12-19T00:16:26+00:00

Requires addition of viewports and alternate framebuffers to greylib
which are essentially similar to the core implementation except that
the framebuffer can be any size and relationship to a viewport. Drawing
is always fully clipped to the intersecting area.

Adapt oscilloscope.c to the API change. FFT will use the new features
(later update).

Get rid of silly and wrong lcd_bmp_part use in OSD. Remove it from
plugin API (must be made incompatible now).

Speed up mono bitmap drawing on horizontally packed greyscale targets (greyscale iPods). Average speedup is 80% on PP5002, and 55% on PP502x. * Simplify mono bitmap drawing in the 16 bit driver and the greylib a bit, also giving a slight speedup (3% on PP502x, 1.5% on coldfire).

Use pre-multiplication in scaler to save one multiply per color component on ARM and Coldfire, at the cost of an extra add/shift in the horizontal scaler to reduce values to a workable range. SH-1 retains the same basic math, as

2009-05-26T20:00:47+00:00

the use of 16x16->32 hardware multiplication in the earlier scaler stages saves more than removing the 32x32->40 multiply to descale output.

Split 8-bit-to-native conversion in bmp.c into a function, add support for plugging unscaled output in BMP and JPEG loaders, use output_row_8_native in JPEG decoder when possible.

Optimize hline, fillrect and mono bitmap drawing for chunky displays (16 bit colour and greylib). Speeds up text rendering by 20..45% on colour coldfire, by 30..50% on colour ARM, and is noticeable in archos pictureflow.

loader-initialized global plugin API:

2009-01-16T10:34:40+00:00

struct plugin_api *rb is declared in PLUGIN_HEADER, and pointed to by
__header.api

the loader uses this pointer to initialize rb before calling entry_point

entry_point is no longer passed a pointer to the plugin API

all plugins, and pluginlib functions, are modified to refer to the
global rb

pluginlib functions which only served to copy the API pointer are
removed
