I need some arrow icons similar to

pointing up, down, left, and right. Actually just give me one arrow and I can rotate it myself.

This is going to be used for text boxes (dialogue windows) and option boxes (e.g. inventory lists) to indicate that there is more content than is currently displayed on the screen. They'll likely go in either the top right or bottom right corners of the GUI display. Or they might go in both (for dialogue, top arrow at top right to go back and bottom arrow and bottom right to go forward). I also intend to make grayscale versions of whatever I'm given to indicate that the end of an option box or text scrolling has been reached.
Size requirements are kind of loose, but should be small. I think 16x16 pixels would do nicely. Visual aesthetics should match our current menu displays, so avoid cartoonish looks for example.
