No deltas in GDK_SCROLL events on Windows
Steps to reproduce
- Do anything that causes GDK_SCROLL to be emitted
Current behavior
delta_x and delta_y event fields are 0
Expected outcome
delta_x or delta_y event field is not 0 (depending on which direction the scrolling was happening in)
Version information
GTK3, any version, Windows
Additional information
Turns out, delta_(x|y) fields were added somewhere in GTK3 (GTK2 didn't have them), but W32 backend was not updated to set them.
