Allow pasting of tabular data

[Lorp]

In setting up a VF, it is often the case that a spreadsheet is used to keep track of correspondences between a designer’s values (often measured in stem widths) and intended OpenType values, with arbitrary methods used to calculate or judge the correspondences.

Fencer would benefit from a textbox accepting input copied from a spreadsheet, accepting either 2-column (1-axis mappings) or 4-column (2-axis mappings). If 2 columns are received, then Fencer’s current X axis is used; if 4 columns are used, then Fencer’s current X and Y axes is used.

In this example, we have selected Weight on Fencer’s X axis, Width on Fencer’s Y axis, then wish to map various input values of Weight and Width to output values of Weight and Width.

Input X	Input Y	Output X	Output Y
200	75	210	71
300	75	340	71
400	75	400	71
500	75	550	72
600	75	640	75
700	75	730	80
800	75	810	84
900	75	900	86

Copying directly from a spreadsheet, and Fencer handling the tab delimited data, is more convenient than editing XML by hand.
