Presumably last release of ver. 1

Before continuing to some new ideas, which may or may not result in new scene structure, Version №1 needs to be fixed at it's final fully operational state. So here the last release of Version №1 go.

Till the next version!

Maintenance

Numerous tiny changes, mostly of interest for developers, like moving many functions to private. Fixed some very rare events sequences causing uncomfortable results with GUI.

Having a ReST

Update includes newes versions of image import modules, and general docstrings improvements.

Bugfix

Randomly capitalized extensions handling bug discovered and fixed.

Acceleration

Export acceleration (ca. 20% on my system) due to improved write buffering. Minor scene legibility updates.

Maintenance

Maintenance update, mostly due to PyPNM update to ver. 2.21.2.2 "Victory II", more resource saving as compared to 1.17.9.34 "Victory".

1.20.20.1 Maintenance

Maintenance update, code harmonization, improved GUI, etc.

Functional transparency

Per-thingie filter and transmit changed from global constants to functions of source image brightness and alpha, allowing better control of transparent objects appearance.

Note that this lead to changing preset structure.

Also some minor improvements implemented, as always.

12 June "Generatio"

Main program GUI improvements ans unification. Main modules remain the same as for 9 May "Victory".

1.16.20.20 New GUI

New, more compact menu-based GUI, with Photoshop-like zooming plus mouse wheel zooming, and other interface improvements.
