9713 837 d 11 h dunkaist /programs/develop/libraries/libs-dev/ libimg: Implement more bit depth conversion routines  
9640 862 d 23 h leency / add KMatrix into Appearance app  
9273 923 d 15 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 1244 d 7 h dunkaist /programs/ kiv and libimg.asm: Follow asm style guide, no semantic changes.  
8463 1252 d 22 h IgorA /programs/develop/libraries/libs-dev/ libimg: can save 32 bit png  
8449 1255 d 14 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 1259 d 19 h IgorA /programs/ tinygl: add some double functions, add bcc32 example
libimg: small optimize		  
8399 1260 d 15 h dunkaist /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix transparency in indexed png images.  
8395 1260 d 18 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: export img.resize_data  
8394 1260 d 19 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 1263 d 9 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 1265 d 18 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: Add and export img.blend function  
7735 1541 d 23 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 2031 d 19 h dunkaist /programs/develop/libraries/libs-dev/libimg/bmp/ Libimg: Fix bug with 16-bit BMP padding.  
7279 2203 d 19 h IgorA /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix save small png images  
7105 2399 d 15 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 2585 d 3 h IgorA / update docs sys function 54.1  
6888 2596 d 2 h IgorA /programs/ add filter 'paeth', fix in 'build_bl_tree'  
6883 2608 d 5 h IgorA /programs/ fix continue crc calculation in 'archiver.obj'  
6881 2613 d 18 h IgorA /programs/ small fixes
