Heh... I just discovered QuantizeBuffer(). I'm finally getting colors in my
image. _However_, it's still not quite right. The grays/whites are slightly
off, with a slight blue tint, but look more white than anything. I don't know
why this is. I would think QuantizeBuffer() would pick the correct colors for
use? Also, I see banding in certain areas of my screen (example, near gradients).
I can see pretty much all colors, though.

Since I'm using GdkPixbufs, I simply grab the pixels:

---
unsigned char *p = pixels + y * rowstride + x * n_channels;
---

Then, I grab the RGB values: p[0], p[1], p[2], respectively. I build up a Red,
Green, and Blue array, then I pass this to QuantizeBuffer(). Then, I write to
EGifPutLine the buffer set by QuantizeBuffer(). I'm using 256 colors, 8BPP.

Any tips?
