 -n :)

If you continue getting noisy chars with -n please send me a patch.

Then, if we play with 2 colors for images and texts it remains simple and with
no deps, and 1bit encoding is rather simple, so we could add a simple binary
compressor algorithm or so to make strings shorter (humans can memorize bitmaps :)

btw the format can be something like:


The 'problem' is that we should be able to define the size of the icon. And this
must be problematic and make the code more difficult with variable length strings,
buffers and so, code will be larger and not more useful.

What we can do is to define the color palete and the depth before providing the bitmap
in a format like:


 We can get the foreground color with ^fg() and the background one with ^bg(). But
what about the rest?

The resolution also anoyis me because i don't know how to manage this. probable to make
this stuff easier and simpler we can just provide proportional bitmaps (N x N) and not
(M x N). And only 2 colors:


  ^.---- this is 32x32 pixels image with the content defined by the following string.

The string can be encoded in base64 or something more optimal than plain hexadecimal.

The problematic I see with 2 color images is that it's not very nice graphically talking
and if you're drawing a diagonal line you'll get an ugly stairs effect.

Another random idea is to provide a multiple color layer pushing one color on top of the
previous one, like splitting the image per colors and serialize each color:


So, only the defined bits will be colorized, the other will be ignored (alpha-like)

arf arf arf :) let me know what do you think about all these things.
