Updates to backend libraries including Tacent (0.8.1), GLFW (3.3.2), zlib (1.2.11) and OpenEXR (2.5.3). Added new 'transparent work area' feature so that images with alpha can be displayed over whatever you have on your desktop, Open 'Settings' to turn this on and off. Requires restart of viewer for changes to take effect.
Fixes and Improvements:
- New OpenEXR lib will load faster.
- Changing slideshow duration takes effect immediately.
- Auto properties editor window no longer appears automatically while slideshow playing.
- Reticle only visible if a colour-inspector (menubar or details) is visible.
- Reticle will not disappear if mouse is close enough. Details always forces reticle to be visible.
- Bottom control buttons and next/prev side butons will not disappear if mouse is in the vicinity.
