A LuaJIT interface to FreeImage

*Note*: this FreeImage interface supports handling unicode filenames on Windows.  

In order to use this feature, make sure your lua script files are UTF-8 encoded.

# Usage #

```lua

require 'fi'

---

# convert image format

convert('*.webp', 'tiff')

# convert image format and bpp

convbpp('*.png', 32, 'bmp')

# convert image format with quality setting

convert('1.png', '1.jpg', 90)

# alpha composite with 24bpp background 8bpp foreground

back = open('rgb24.bmp')

front = open('alpha8.bmp')

back_resized = scale(back, getw(front), geth(front))

back_rgba = to32(back_resized)

save(back_resized, 'resized.png', 9)

save(back_rgba, 'back.tiff')

out = composite(back_rgba, front)

save(out, 'composite.png')

freeAll({back_resized, front, out, back_rgba})

free(back)

...

```

# windows cmd with TrueType font
