	* tutorials/Straight_Line/exp2.png: As suggested by Seth, I re-did
	the image to get rid of a bug in the original version.

	* tutorials/Custom_Brushes/thumb*.png: Added new 2.0 screenshots.

	* tutorials/Custom_Brushes/thumb*.jpg: Removed.

	* tutorials/Custom_Brushes/index.htrw: Updated for 2.0, fixed
	several typos, replaced the *.jpg links with *.png.  The PNG files
	are significantly smaller and look better.
