* textmodes/tildify.el (tildify-foreach-region-function): New variable specifying a function determining portions of buffer that should be tildified. It allows major modes to create a filtering function more elaborate than a set of regular expressions. Initialised to `tildify--deprecated-ignore-evironments' by default to handle now deprecated `tildify-ignored-environments-alist' variable. (tildify--foreach-region): A new function that takes `tildify-foreach-region-function' into account and calls callback for regions of the buffer that should be tildified. (tildify-foreach-ignore-environments): A new function which can be partially applied and used as `tildify-foreach-region-function'. (tildify-ignored-environments-alist, tildify--pick-alist-entry): Mark as obsolete. (tildify--find-env): Rename from `tildify-find-env' and mark as obsolete. (tildify--deprecated-ignore-evironments): New function, immediately marked as obsolete, used to handle deprecated `tildify-ignored-environments-alist'. * textmodes/tex-mode.el (tex-common-initialization): Set `tildify-foreach-region-function' variable in all variants of TeX mode since `tildify-ignored-environments-alist' variable is now empty by default. * nxml/nxml-mode.el (nxml-mode): Ditto in `nxml-mode'. * textmodes/sgml-mode.el (sgml-mode): Ditto in `sgml-mode'.
