Move functions from skia/ext to app/gfx where possible: most of skia_utils.* and image_operations.* can be moved because they are not used by WebKit code.
This also fixes the spelling of "Convolusion" to "Convolution" and updates some copyrights. This is a re-do of r26975, this time with WebKit update and some fixes to compile on Mac and Linux.
