/*
  How Properties of Mime Types are used by SQL Mode
  =================================================

  keywords:
    A list of keywords you want to be highlighted.
  builtin:
    A list of builtin types you want to be highlighted (if you want types to be of class "builtin" instead of "keyword").
  operatorChars:
    All characters that must be handled as operators.
  client:
    Commands parsed and executed by the client (not the server).
  support:
    A list of supported syntaxes which are not common, but are supported by more than 1 DBMS.
    * ODBCdotTable: .tableName
    * zerolessFloat: .1
    * doubleQuote
    * nCharCast: N'string'
    * charsetCast: _utf8'string'
    * commentHash: use # char for comments
    * commentSlashSlash: use // for comments
    * commentSpaceRequired: require a space after -- for comments
  atoms:
    Keywords that must be highlighted as atoms,. Some DBMS's support more atoms than others:
    UNKNOWN, INFINITY, UNDERFLOW, NaN...
  dateSQL:
    Used for date/time SQL standard syntax, because not all DBMS's support same temporal types.

     * Element.transform
     [ method ]
     **
     * Adds transformation to the element which is separate to other attributes,
     * i.e. translation doesn’t change `x` or `y` of the rectange. The format
     * of transformation string is similar to the path string syntax:
     | "t100,100r30,100,100s2,2,100,100r45s1.5"
     * Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
     * scale and `m` is for matrix.
     *
     * There are also alternative “absolute” translation, rotation and scale: `T`, `R` and `S`. They will not take previous transformation into account. For example, `...T100,0` will always move element 100 px horisontally, while `...t100,0` could move it vertically if there is `r90` before. Just compare results of `r90t100,0` and `r90T100,0`.
     *
     * So, the example line above could be read like “translate by 100, 100; rotate 30° around 100, 100; scale twice around 100, 100;
     * rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin
     * coordinates as optional parameters, the default is the centre point of the element.
     * Matrix accepts six parameters.
     > Usage
     | var el = paper.rect(10, 20, 300, 200);

     | el.transform("t100,100r45t-100,0");
     | // if you want you can append or prepend transformations
     | el.transform("...t50,50");
     | el.transform("s2...");
     | // or even wrap
     | el.transform("t50,50...t-50-50");
