8497 1244 d 3 h dunkaist /programs/ kiv and libimg.asm: Follow asm style guide, no semantic changes.  
8463 1252 d 19 h IgorA /programs/develop/libraries/libs-dev/ libimg: can save 32 bit png  
8449 1255 d 11 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 16 h IgorA /programs/ tinygl: add some double functions, add bcc32 example
libimg: small optimize
 
8399 1260 d 12 h dunkaist /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix transparency in indexed png images.  
8395 1260 d 15 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: export img.resize_data  
8394 1260 d 16 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 6 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
 
8342 1265 d 15 h dunkaist /programs/develop/libraries/libs-dev/.test/ Add img.blend example, add libimg examples to autobuild  
8341 1265 d 15 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: Add and export img.blend function  
7735 1541 d 20 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.
 
7705 1635 d 10 h dunkaist /programs/develop/libraries/libs-dev/libini/ libini: Fix ini.del_section to not lose the last byte of a file.  
7523 2031 d 15 h dunkaist /programs/develop/libraries/libs-dev/libimg/bmp/ Libimg: Fix bug with 16-bit BMP padding.  
7279 2203 d 16 h IgorA /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix save small png images  
7105 2399 d 11 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.
