/* Incoming Bytes Event pipeline
This section deals with decoding the incoming character stream.
Decoding means here, that the stream is first separated into `tokens'
which are then mapped to a `meaning' provided as operations by the
`Screen' class or by the emulation class itself.
The pipeline proceeds as follows:
- Tokenizing the ESC codes (onReceiveChar)
- VT100 code page translation of plain characters (applyCharset)
- Interpretation of ESC codes (tau)
The escape codes and their meaning are described in the
technical reference of this program.
*/
// Tokens ------------------------------------------------------------------ --
/*
Since the tokens are the central notion if this section, we've put them
in front. They provide the syntactical elements used to represent the
terminals operations as byte sequences.
They are encodes here into a single machine word, so that we can later
switch over them easily. Depending on the token itself, additional
argument variables are filled with parameter values.
The tokens are defined below:
- CHR - Printable characters (32..255 but DEL (=127))
- CTL - Control characters (0..31 but ESC (= 27), DEL)
- ESC - Escape codes of the form <ESC><CHR but `[]()+*#'>
- ESC_DE - Escape codes of the form <ESC><any of `()+*#%'> C
- CSI_PN - Escape codes of the form <ESC>'[' {Pn} ';' {Pn} C
- CSI_PS - Escape codes of the form <ESC>'[' {Pn} ';' ... C
- CSI_PR - Escape codes of the form <ESC>'[' '?' {Pn} ';' ... C
- CSI_PE - Escape codes of the form <ESC>'[' '!' {Pn} ';' ... C
- VT52 - VT52 escape codes
- <ESC><Chr>
- <ESC>'Y'{Pc}{Pc}
- XTE_HA - Xterm hacks <ESC>`]' {Pn} `;' {Text} <BEL>
note that this is handled differently
The last two forms allow list of arguments. Since the elements of
the lists are treated individually the same way, they are passed
as individual tokens to the interpretation. Further, because the
meaning of the parameters are names (althought represented as numbers),
they are includes within the token ('N').

Instead of keeping an explicit state, we deduce it from the
token scanned so far. It is then immediately combined with
the current character to form a scanning decision.
This is done by the following defines.
- P is the length of the token scanned so far.
- L (often P-1) is the position on which contents we base a decision.
- C is a character or a group of characters (taken from 'tbl').
Note that they need to applied in proper order.
