As promised, here is a maintenance release of Thorium M109 for Windows 7/8/8.1!
Backported some stuff, and bumped minor rev number 109.0.5414.120 > 109.0.5414.139 which includes security fixes from upstream Chromium.

– Compiled with Polly enabled
– Pre-compiling of inline scripts enabled
– Added "Ctrl+Shift+Q" keyboard shortcut to close all windows.

• Backported more optimization flags for V8, Chromium's Javascript engine, from the M111 release.

• Backported five new new chrome://flags flags from the M110 & M111 release:
  – chrome://flags/#force-gpu-mem-available-mb - Set available VRAM to be used by Thorium. Options are 128, 256, 512, and 1024 Mb. Useful for systems with very low or very high video memory. The default (if unset) is 512 Mb.
  – chrome://flags/#enable-native-gpu-memory-buffers - Enable native CPU-mappable GPU memory buffer support on Linux. (Linux only) You can see the effect of this on chrome://gpu in the "GpuMemoryBuffers Status" section.
  – chrome://flags/#double-click-close-tab - A flag that @gz83 came up with and we both implemented. Allows you to close a tab by simply double-clicking on it, similar to an option in Vivaldi.
  – chrome://flags/#show-fps-counter - Show a F.P.S. counter on each display, which also shows used/available GPU memory. Useful for Web development.
  – chrome://flags/#media-router to enable/disable the media router, i.e. for Cast.

• Logo has had padding removed, and a new logo was created for the windows installer .exe.

• Thorium mascot image added to chrome://version page, under the copyright (for fun)
