Person c3078f018a --User changes 
-Update various tooltips.
 -Increase precision of affine and xaos spinners.
 -Increase precision of fields written in Xml files to 8.

--Bug fixes
 -When rendering on the CPU, if the number of threads didn't divide evenly into the number of rows, it would leave a blank spot on the last few rows.
 -Fix numerous parsing bugs when reading .chaos files.
 -Added compatibility fixes and/or optimizations to the following variations: asteria, bcircle, bcollide, bipolar, blob2, btransform, cell, circlecrop, circlecrop2, collideoscope, cpow2, cropn, cross, curl, depth_ngon2, depth_sine2, edisc, eRotate, escher, fan2, hex_rand, hypershift, hypershift2, hypertile1, julia, julian, julian2, juliaq, juliascope, lazyjess, log, loonie2, murl, murl2, npolar, oscilloscope2, perspective, phoenix_julia, sphericaln, squish, starblur, starblur2, truchet, truchet_glyph, waffle, wavesn.
