[ptx] content for new "Tip of the day" dialog

[Pablo d'Angelo]

Hi!

Douglas Wilkins has added a "Tip of the day" window to hugin.

As a start we have added some tips. However, there should be more of 
them. So if you miss something lets add it!

Also, probably the tips I have written could be expressed more 
succinctly and to the point. Here is the current list:

I hope nobody is too tired by reading it.

======

To scroll both the images in the control points tab, hold the shift key 
while moving the mouse.

The control key or the middle mouse button can be used to pan one image 
in the control points tab.

Rotating the camera around the nodal point makes panorama creation a lot 
easier

If the panorama looks nice but the horizon is curved, select a new 
anchor position, or add vertical or horizontal control points.

Horizontal or vertical control point pairs can be set by selecting the 
same image on both sides of the control points tab

Control points should be placed on static objects. Avoid placing them 
people, trees and other moving or deforming objects

Images can also be added to hugin via drag and drop.

Spread control points as far as possible. Close control points do not 
define the relative orientation between images well.

The Fine Tune button can be used to find a better position for the point 
in the right image for an already selected point.

Editing the panorama in multiple layers with The Gimp or Photoshop 
offers many creative possibilities.

The multilayer tiff file output can be read by The Gimp 2.0 or higher.

You can press the middle mouse button to pan images in the control 
points tab.

The "f" key is the shortcut for Fine Tune button.

Pressing "Del" will remove the currently selected control point.

Press "0" in the control points tab to zoom out to full view.

Press "1" in the control points tab to zoom out to 100% view.

The external tools autopano and autopano-sift can be used to create 
control points automatically.

Enblend can be used to smoothly blend the panorama. Use it from within 
hugin by selecting \"high quality tiff file\" as output.

After enblend has blended the panorama, the remapped output images 
(available in the same directory as the panorama image) can be used to 
retouch the panorama in The Gimp or Photoshop.

enblend 2.1 for Windows cannot handle compressed TIFF images. Switch to 
another version if it doesn't work.

hugin and other free panoramic software is discussed on the ptx email 
list. http://www.email-lists.org/mailman/listinfo/ptx.

The Panorama Tools, on which hugin is based were written by Helmut Dersch.

The precision of \"fine tuning\" control points can be improved by 
enabling rotation search. This is essential for fisheye and wide angle 
images.

Multiple images can be selected in the image and lens tabs. Command will 
act on all selected images.

Lens parameters may vary with changing focus. For best results, 
calibrate the parameters using know settings and reuse them later.

Optimisation of all distortion parameters everything makes only sense 
with heavily overlapping images and many well distributed control points.
