+# Experimental option that does a number of things to make truly smooth scrolling possible:
+#
+# * Enables hardware-accelerated scrolling.
+#     Blit-acceleration copies as much of the rendered area as possible and then repaints only newly exposed region.
+#     This helps to improve scrolling performance and to reduce CPU usage (especially if drawing is compute-intensive).
+#
+# * Enables "true double buffering".
+#     True double buffering is needed to eliminate tearing on blit-accelerated scrolling and to restore
+#     frame buffer content without the usual repainting, even when the EDT is blocked.
+#
+# * Adds "idea.true.smooth.scrolling.debug" option.
+#     Checks whether blit-accelerated scrolling is feasible, and if so, checks whether true double buffering is available.
+#
+# * Enables handling of high-precision mouse wheel events.
+#     Although Java 7 introduced MouseWheelEven.getPreciseWheelRotation() method, JScrollPane doesn't use it so far.
+#     Depends on the Editor / General / Smooth Scrolling setting, remote desktop detection and power save mode state.
+#     Ideally, we need to patch the runtime (on Windows, Linux and Mac OS) to improve handling of the fine-grained input data.
+#     This feature can be toggled via "idea.true.smooth.scrolling.high.precision" option.
+#
+# * Enables handling of pixel-perfect scrolling events.
+#     Currently this mode is available only under Mac OS with JetBrains Runtime.
+#     This feature can be toggled via "idea.true.smooth.scrolling.pixel.perfect" option.
+#
+# * Enables interpolation of scrolling input (scrollbar, mouse wheel, touchpad, keys, etc).
+#     Smooths input which lacks both spatial and temporal resolution, performs the rendering asynchronously.
+#     Depends on the Editor / General / Smooth Scrolling setting, remote desktop detection and power save mode state.
+#     The feature can be tweaked using the following options:
+#       "idea.true.smooth.scrolling.interpolation" - the main switch
+#       "idea.true.smooth.scrolling.interpolation.scrollbar" - scrollbar interpolation
+#       "idea.true.smooth.scrolling.interpolation.scrollbar.delay" - initial delay for scrollbar interpolation (ms)
+#       "idea.true.smooth.scrolling.interpolation.mouse.wheel" - mouse wheel / touchpad interpolation
+#       "idea.true.smooth.scrolling.interpolation.mouse.wheel.delay.min" - minimum initial delay for mouse wheel interpolation (ms)
+#       "idea.true.smooth.scrolling.interpolation.mouse.wheel.delay.max" - maximum initial delay for mouse wheel interpolation (ms)
+#       "idea.true.smooth.scrolling.interpolation.precision.touchpad" - precision touchpad interpolation
+#       "idea.true.smooth.scrolling.interpolation.precision.touchpad.delay" - initial delay for precision touchpad interpolation (ms)
+#       "idea.true.smooth.scrolling.interpolation.other" - interpolation of other input sources
+#       "idea.true.smooth.scrolling.interpolation.other.delay" - initial delay for other input source interpolation (ms)
+#
+# * Adds on-demand horizontal scrollbar in editor.
+#     The horizontal scrollbar is shown only when it's actually needed for currently visible content.
+#     This helps to save editor space and to prevent occasional horizontal "jitter" on vertical touchpad scrolling.
+#     This feature can be toggled via "idea.true.smooth.scrolling.dynamic.scrollbars" option.
