Qt terminal

[Petr M. <mi...@ph...>]

I've updated the Qt library to 4.5 and thus I could try the new Qt terminal. 
It works well. I have few comments:

- "Export to pdf" produces file with the plot on top of the paper sheet. 
  I would like if the dialog can give options for:
	- Center the plot on the paper.
	- Export only the figure (i.e. no page, but cropped image), as
	  "set term pdf" is doing.

- Could the "Export to image" ask for the image size? E.g. 800x600 etc.

- If antialias is off, then rotation by mouse of "set pm3d; splot x*x" has 
  the same speed as x11 terminal. If antialias is on, then it rotates much 
  slower.

- The first two zoom icons should rather have arrows (<-) and (->) 
  instead of (-) and (+).

- I think the terminal could write its own set-up as wxt is doing, i.e. 
	$HOME/.gnuplot-qt

- I think the default font could be saved in that config file (having a 
  button for font dialog in the setup dialog).

- I would enjoy very much the "space" hotkey functionality as in other 
  terminals.
