Updated: mintty 2.6.1

[Thomas Wolff]

I have uploaded mintty 2.6.1 with the following changes:

   * Released Sixel graphics support in a stable version. With this nice 
feature, you can embed graphics output in the terminal, for example with 
gnuplot.

   * Tweaked DPI scaling to avoid terminal resizing on font selection 
(~#492).
   * Enabling auto-scaling of window decoration (#547, #517, thanks to 
Jason Mansour #588).

   * Option AllowSetSelection to enable OSC 52 control sequence to set 
clipboard for pasting (#258, thanks to kangjianbin).
   * Tweaked underscore cursor position, considering row spacing (#589).

   * Retaining config file comments (#574).
