While this is backwards compatible, the new form uses optional modifiers. This PR updates the documentation, the example script in the cookbook, but have not changed the test scripts (yet) to make sure both forms work.

While @Esteban82 has approved this one (since it works), if anyone has comments or changes to the particular choices of modifiers then now is a good time. FYI, here is the three test results for varying altitude, azimuth, and view restriction: Altitude: Azimuth: View: |

Is this supposed to work this way? I get a flip image when I add +du to the width

New syntax
-Jg|Glon0/lat0/scale|width[+aazimuth][+ttilt][+vvwidth/vheight][+wtwist][+zaltitude]
Old syntax
-Jg|Glon0/lat0/altitude/azimuth/tilt/twist/Width/Height/scale|width
I have added three new tests that explores variations in azimuth, altitude, and view window. I will add similar tests for twist and tilt later.
The documentation, doc examples, doc scripts and animations using the perspective projection have been updated to reflect the new syntax. We will leave old tests scripts for backwards testing and add new scripts using the modernized format.
