opentrack 2022.1.0

Fixes

• fix a bug introduced in opentrack 2021.1.3 that caused choppy output with the PT tracker (thanks to @dglava, @Vortex76, @Len62, @animusVoxxx, @3itZ as well as the Russian IL2 forum). it should work as well as 2021.1.2 even when not using the point filter (see 4b77e13, f51d533, 3272048).
• grayscale conversion methods are now clearly described in the PT tracker. obsolete averaging method is gone, and hardware-based grayscaling with the ps3eye open driver is optional and off by default (see f531c31).
• fix a bug where any selection for freetrack output other than 'enable both' caused both registry keys to be cleared (see 7c8fd62).
• the neuralnet tracker works with no VC++ redistributables installed, particularly on Windows 7 (build only fix).

Features

• module dialogs are now drawn inside the options window. sponsored by TrackHat Ltd. dialogs that haven't been converted yet are drawn normally.
