I renamed "OpenGL Depth Picking" to "GPU Depth Picking" so the UI text for the option is not specific to the graphics API.
I changed the tooltip for OpenGL Depth Picking from "Use the depth buffer for picking 3D View selection (without this the front most object may not be selected first)" to "When making a selection in 3D View, use the GPU depth buffer to ensure the frontmost object is selected first"
In Viewport > Display. I changed "Show" to "Text Info Overlay" since the options only "show" when the text info overlay is enabled.
I made capitalization consistent in places and reworked a few other labels and tooltips.
Let me know if I should revert or tweak any change.
With this patch, I did not change anything in the animation tab of the preferences, but it could also use some similar improvements.
