Add a idea.properties file for Studio.
Launching Studio with a custom idea.properties files allows to
have a separate profile of Android Studio for work with AndroidX.
To use this launch Studio with setting STUDIO_PROPERTIES env variable.
This CL also adds an example linux destkop shortcut entry.

+# Guide for setting up a separate profile for Android Studio
+
+It can be helpful to have a separate profile of Android Studio when
+working on AndroidX as we use prebuilts of an SDK instead of public SDK.
+Launching Studio with a custom idea.properties files allows to
+have a separate profile of Android Studio for work with AndroidX.
+
+To use this launch Studio with setting STUDIO_PROPERTIES env variable to point
+to idea.properties in this checkout that sets custom `idea.config.path` and
+`idea.system.path`. `sample-androidx-canary.desktop` is an example Linux desktop
+shortcut entry.
+
+[More details on this on Jetbrains website](https://intellij-support.jetbrains.com/hc/en-us/articles/207240985-Changing-IDE-default-directories-used-for-config-plugins-and-caches-storage?page=2)

+# 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.
