// NEW mtextcontrol interface:
//
// obtain the full mtextcontrol interface from the library. it is much faster as use of 
// miranda core CallService to access to mtextcontrol (no core traffic).
// This interface provides full access to mtextcontrol internal functions,
// thus enabling devs to fully utilize the mtextcontrol API.
// All functions will be exported as miranda services for compatibility.
//
// the interface is populated during the Load(PLUGINLINK *link) handler, so you can assume it is ready when Miranda
// throw the ME_SYSTEM_MODULESLOADED event and you can generate a warning in your ModulesLoaded() when
// it depends on the mtextcontrol interface and the mtextcontrol plugin is missing.
// 
// example:
// 
// MTEXT_INTERFACE MText = {0};
// 
// 	mir_getMTI(&MText);
// 
// all interface function designed as old mtextcontrol helper functions.
// therefore it is easy to convert your old plugin code to new interface.
//
// example:
//
// old code: MTextCreate (...
// new code: MText.Create(...
