* We add a button with a link icon to indicate that it goes to the
resource details. We'll re-use the crosshair as a visual metaphor for
any interactive widget that goes to the resource inspector.
* To remove any possible confusion, we change the icon for the texture
list and locked tabs in the texture viewer to not include the link.
Most of the icons in here come from the "Farm-Fresh Web Icons" pack from fatcow.com.

Some icons have special notes:
delete.png is renamed to del.png to avoid obvious clashes with the C++ keyword.
flip_y.png is created just by rotating arrow_left.png to be vertical in the top half of the image, then rotating/flipping it to the bottom half.
upfolder.png is created by pasting arrow_up.png on top of folder.png, then erasing all pixels that overlap the front half of the folder.
action.png and action_hover.png are both based on document_page_next.png, with the little fold removed and colours changed.
control_reverse_blue.png is just control_play_blue.png flipped horizontally.
control_nan_blue.png and control_sample_blue.png are control_cursor_blue with the cursor edited out and replaced with the appropriate symbol. control_base_blue.png is not used directly but is kept in case future additions are needed.
