binds... * ctrl + shift + m1 (in texbro): open shader in external editor misc... * fix: do not unmaximize external shader editor on win * fix: blank cursor in radiant after calling external shader editor on win * fix shader editors stuff for non uindowses * 'Shader Editor Command' preference is available on win (is used, if set; otherwise try default os action for file) * fix: 'Shader Editor Command' preference allows selecting executable via dialog * GDK_HAND2 cursor in clipper tool mode * fix: clipper points have numeric labels * '2d zoom in to mouse pointer' option works for alt + m2 zoom * '3d zoom in to mouse pointer' option (def = yes)
