	* 2D image painting with textures that contained alpha did not work correctly, had been broken for a while. * 2D image panels texture (mask) panels showed wrong buttons for texture overlay. * Texture map mode 3D now also uses masking, like Tiled and Stencil the texture does not move along with the brush so it works fine. * 2D image paint View mapping did not work correct, especially noticeable with Rake rotation. * Masking is now disabled for the smear tool, this can't really work because the original image is constantly changing and gave artifacts.

	old issue, the formulas here were never quite right, should all work ok now with byte and float images. Some differences: * Colors with zero alpha from the background will never have an influence, so you don't get alpha fringes when painting over such areas. This does give hard edges when looking at the RGB channels alone, but there's no way to avoid that and fringes at the same time, same behavior as other painting apps. * Add/Subtract/Multiply/Lighten/Darken now leave the alpha channel unchanged and work only the RGB channels, again same behavior as many other apps. * Erase/Add alpha now compensates for premultiplied float images to keep the straight RGB colors the same. Next: fix projection painting.
