Redefine all this to make some sense. In particular: * Drop CUR_DEFAULT, which is CUR_UNDERLINE. CUR_DEFAULT was used only for cur_default variable initialization, so use CUR_UNDERLINE there to make obvious what's the default. * Drop CUR_HWMASK. Instead, define CUR_SIZE() which explains it more. And use it all over the places. * Define few more masks and bits which will be used in next patches instead of magic constants. * Define CUR_MAKE to build up cursor value.
