José Matox 8fc2c1dd05 * LyX.py 
* lyx_1_1_5.py
	* lyx_1_2.py
	* lyx_1_3.py
	* lyx_1_4.py
	* lyx_1_5.py

	* parser_tools.py: remove functions that are not generic, i.e.
assume a specific pattern for the file format, and move them to the
places where they are used.

# Here we know that this box is not supported in file format 224.
# Therefore we need to convert it to ERT. We can't simply convert
# the beginning and end of the box to ERT, because the
# box inset may contain layouts that are different from the
# surrounding layout. After the conversion the contents of the
# box inset is on the same level as the surrounding text, and
# paragraph layouts and align parameters can get mixed up.
# A possible solution for this problem:
# Convert the box to a minipage and redefine the minipage
# environment in ERT so that the original box is simulated.
# For minipages we could do this in a way that the width and
# position can still be set from LyX, but this did not work well.
# This is not possible for parboxes either, so we convert the
# original box to ERT, put the minipage inset inside the box
# and redefine the minipage environment to be empty.
# Commands that are independant of a particular box can go to
# the preamble.
# We need to define lyxtolyxrealminipage with 3 optional
# arguments although LyX 1.3 uses only the first one.
# Otherwise we will get LaTeX errors if this document is
# converted to format 225 or above again (LyX 1.4 uses all
# optional arguments).
