Support for DirectX Texture Compression would be great.

Typically an image using DXTC is 50% smaller than the
same image as a 8bit paletted png.

So, a 32bit RGBA png at 576k can be reduced to 96k
using DXTC. Plus there would be very little visible
difference in image quality.

The most common formats using DXTC are:

DXT1 - Four bit (compressed) RGB + 1-bit alpha
DXT3 - Four bit (compressed) RGB + 4-bit explicit alpha

P8 - 8-bit palettized (256 color) Even though they are
uploaded to the video card as a full 32-bit RGBA texture,
when properly quantized a P8 can look identical to the
original 24-bit image, while still offering a 75% savings in
disk and system memory.
