    Simple helper to use dlg_proc(). See wiki.freepascal.org/CudaText_API#dlg_proc

    Main features:
    - All controls are created once then some of them can be changed via callbacks (attribute 'call').
    - The helper stores config version of form's and control's attributes.
      So the helper can return two versions of attributes: configured and actual (live).
    - Helper marshals complex data ('items' for type=list/combo/..., 'val' for type=memo)
    - Helper can to save/restore form position and sizes to/from file "settings/forms data.json".
      Key for saving is form's 'cap' (default) or a value in call BaseDlgAgent(..., option={'form data key':'smth'})
      If value of 'form data key' is empty then helper doesnt save/restore.

    Callback cannot add new controls or change type values.
    
    Useful methods of agent
    - agent.cattr(name, '??', live=T)               To get a control actual/configured attribute
    - agent.cattrs(name, ['??'], live=T)            To get dict of a control listed actual/configured attributes
    - agent.fattr('??', live=T)                     To get actual/configured form attribute
    - agent.fattrs(live=T, ['??']=None)             To get actual/configured all/listed form attributes
    
    Tricks
    Automatically set some values for attributes
        - 'act':True    If 'call'   set in a control (not 'button')
        - 'w_min':w     If 'resize' set in the form
        - 'h_min':h     If 'resize' set in the form

    Example. Dialog with two buttons.

    Helper to use dlg_proc(). See wiki.freepascal.org/CudaText_API#dlg_proc

    Main base features :
    - All controls are created once then some of them can be changed via callbacks (attribute 'call').
    - The helper stores config version of form's and control's attributes.
      So the helper can return two versions of attributes: configured and actual (live).
    - Helper marshals complex data ('items' for type=list/combo/..., 'val' for type=memo)
    - Helper can to save/restore form position and sizes to/from file "settings/forms data.json".

    Main extra features:
    - Helper handles attributes names of controls
        Helper adds short synonyms: 
            cid is name
            tp  is type
            fid is focused
        Helper adds new attributes to simplify config: 
            l,r,t,b,tid,a,aid 
        are translated to live 
            x,y,w,h,a_*,sp*
    - Helper allows to aligns texts from linear controls (by tid attribute)

    Terms
        conf-attr - configured attribute (key and value passed to agent from plugin)
        live-attr - actual attribute     (key and value taked from dlg_proc)
    
    Rules
    1. All conrols have conf-attr 'cid'|'name'. It must be unique.
    2. All conrols have conf-attr 'tp'|'type'. 
        Value of 'tp'|'type' can be any API values or shortened variants from REDUCTIONS.
    3. Conrol position can be set 
        - directly by x,y,w,h
        - computed by enough subset of l,r,w,t,b,h (x=l, y=t, l+w=r, t+h=b)
        - computed by tid (refer to cid|name of control, from which to get t and add a bit to align texts)
    4. Controls values (attribute 'val') can be passed to agent as separate collection:
        - parameter 'vals' to call constructor
        - key 'vals' in dict to return from callback
    5. Need focused control cid can be passed to agent
        - parameter 'fid' to call constructor
        - key 'fid' in dict to return from callback
        - key 'fid' into parameter 'form'
       Live focused control cid can be asked as agent.fattr('fid')
    6. Anchors 'aid' and 'a' are used to plan control's position on form resize. 
        Note: agent's anchors cannot set initial control position (except to center control).
        'aid' points to a tagret: form (empty value, default) or cid.
        'a' has string value which can include character:
            - |     to center           the control by horz/vert with the target
            t T     to anchor top    of the control to top/bottom of the target
            b B     to anchor bottom of the control to top/bottom of the target
            l L     to anchor left   of the control to left/right of the target
            r R     to anchor right  of the control to left/right of the target
        Padding with target (live-attrs 'sp_*') are auto-calculated by initial positions of both elements.
        Examples
            a='|lR'     
    7. Format of callback for a control
        def callname(name_of_event_control, agent):
            'smth'
            return None                         #   To hide form
            return {}                           #   To keep controls and form state
            return {'ctrls':[(nm,{...})]        #   To change controls with pointed names
                   ,'vals':{nm:...}             #   To change controls 'val' with pointed names
                   ,'form':{...}                #   To change form attributes
                   ,'focused':name_to_focus     #   To change focus
                   ,'fid':cid_to_focus          #   To change focus
                   }                            #   Any key ('ctrls','vals','form','fid','focused') can be ommited.
        Callback cannot add/del controls or change cid,type,a,aid
        Callback have to conside the form as it has initial size - agent will recalculate to actual state.
        Useful methods of agent
        - agent.cattr(cid, '??', live=T)        To get a control actual/configured attribute
        - agent.cattrs(cid, ['??'], live=T)     To get dict of a control listed actual/configured attributes
        - agent.cval(cid, live=T)               To get actual/configured 'val' attribute (short of agent.cattr(cid, 'val'))
        - agent.cvals([cid], live=T)            To get dict of actual/configured 'val' the listed attributes
        - agent.fattr('??', live=T)             To get actual/configured form attribute
        - agent.fattrs(live=T, ['??']=None)     To get actual/configured all/listed form attributes
    8. Match of different conf-attr and live-attr keys: 
        cid     name
        tp      type
        l       x 
        r       x+w
        t       y
        b       y+h
        tid     y
        aid     a_*[0]
        a       a_*[1], sp*
        fid     focused
        call    callback
    9. List of same conf-attr and live-attr keys
        w h 
        cap hint 
        props 
        color 
        font_name font_size font_color font
        val
        act
        en vis 
        tag 
        tab_stop tab_order
    10. Tricks
        - 'tid' vertical aligns not a pair of controls themself but text in its. 
          For this it uses platform specific data. The data can be configured by call dlg_valign_consts()
        - If cap of a label starts with '>' then the character is cut and 'prop' set to '1' to right alignment
        - Attributes
            def_bt spinedit url grid at_botttom brdW_fillC_fontC_brdC ro_mono_brd
          are used as temporary and readable version of 'prop'. 
          They can be use to configure as others but key to ask is 'prop'.
        - Attribute 
            sto     tab_stop
          is used as temporary version of 'tab_stop'. 
    
    Example. Horz-resized modal dialog with two buttons. First button is stretched, second is pinned to right.
