Icon drawing

- Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled.

- Made drawing Icons use float coordinates

- Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :)

- Skipped scaling and imbuf copying when icons are OK size

icons and previews

Big commit in orange: Interface icons for materials, textures world and lamp. Also for images in pupmenus. Also preparation for work on using preview images in imagebrowser.
