9713 812 d 14 h dunkaist /programs/develop/libraries/libs-dev/ libimg: Implement more bit depth conversion routines  
9640 838 d 2 h leency / add KMatrix into Appearance app  
9273 898 d 18 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: Avoid SSE pinsrw instruction in blend_mmx.asm

pinsrw can act on MMX registers, but it is still an SSE instruction.		  
8497 1219 d 10 h dunkaist /programs/ kiv and libimg.asm: Follow asm style guide, no semantic changes.  
8463 1228 d 1 h IgorA /programs/develop/libraries/libs-dev/ libimg: can save 32 bit png  
8449 1230 d 17 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: Improve support of transparent PNG images.

* Support grayscale images with alpha channel.
* Support rgb images with transparent color.
* Process 'tRNS' chunk (simple transparency).

Transparent png images were already supported for color type 6, which
is RGBA. Now indexed images (color type 3) can also have transparency
via 'tRNS' chunk data.		  
8408 1234 d 22 h IgorA /programs/ tinygl: add some double functions, add bcc32 example
libimg: small optimize		  
8399 1235 d 18 h dunkaist /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix transparency in indexed png images.  
8395 1235 d 21 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: export img.resize_data  
8394 1235 d 22 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: transparency fixes.

img.convert doesn't make opaque pixels transparent.
gif decoder considers palette pixels opaque.		  
8363 1238 d 12 h leency /programs/ libimg: img.decode now checks that length is not null
WebView: img tag: proceed data-src= if src= is empty, fix crash		  
8341 1240 d 21 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: Add and export img.blend function  
7735 1517 d 2 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: tiff: Don't rely on EOI tag at the end of the strip.

Reference implementation (libtiff) has a workaround: precalculate data
size of the strip and don't rely on EOI tag of specific bit length.

This allow to read some invalid TIFF LZW images by my old scanner.		  
7523 2006 d 21 h dunkaist /programs/develop/libraries/libs-dev/libimg/bmp/ Libimg: Fix bug with 16-bit BMP padding.  
7279 2178 d 22 h IgorA /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix save small png images  
7105 2374 d 18 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: add img.from_file, refactor img.convert.

Add new function, img.from_file: gets file name and returns decoded Image.
Make img.convert code less spaghetti: use jump table, not a chain of jmp's.		  
6891 2560 d 6 h IgorA / update docs sys function 54.1  
6888 2571 d 5 h IgorA /programs/ add filter 'paeth', fix in 'build_bl_tree'  
6883 2583 d 8 h IgorA /programs/ fix continue crc calculation in 'archiver.obj'  
6881 2588 d 21 h IgorA /programs/ small fixes
