9713 833 d 22 h dunkaist /programs/develop/libraries/libs-dev/ libimg: Implement more bit depth conversion routines  
9640 859 d 11 h leency / add KMatrix into Appearance app  
9273 920 d 2 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 1240 d 18 h dunkaist /programs/ kiv and libimg.asm: Follow asm style guide, no semantic changes.  
8463 1249 d 9 h IgorA /programs/develop/libraries/libs-dev/ libimg: can save 32 bit png  
8449 1252 d 1 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 1256 d 6 h IgorA /programs/ tinygl: add some double functions, add bcc32 example
libimg: small optimize		  
8399 1257 d 2 h dunkaist /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix transparency in indexed png images.  
8395 1257 d 5 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: export img.resize_data  
8394 1257 d 6 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 1259 d 20 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 1262 d 6 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: Add and export img.blend function  
7735 1538 d 10 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 2028 d 6 h dunkaist /programs/develop/libraries/libs-dev/libimg/bmp/ Libimg: Fix bug with 16-bit BMP padding.  
7279 2200 d 7 h IgorA /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix save small png images  
7105 2396 d 2 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 2581 d 14 h IgorA / update docs sys function 54.1  
6888 2592 d 13 h IgorA /programs/ add filter 'paeth', fix in 'build_bl_tree'  
6883 2604 d 17 h IgorA /programs/ fix continue crc calculation in 'archiver.obj'  
6881 2610 d 5 h IgorA /programs/ small fixes
