Texture2D.alphaIsTransparency API is editor-only but lives in UnityEngine.dll
-e: Using Texture2D.alphaIsTransparency in a script causes the build to fail with the following error:
error CS1061: Type `UnityEngine.Texture2D' does not contain a definition for `alphaIsTransparency' and no extension method `alphaIsTransparency' of type `UnityEngine.Texture2D' could be found (are you missing a using directive or an assembly reference?)
-repro:
* Open attached example project.
* Go to File > Build Settings
* Select PC, Mac & Linux Standalone
* Select Target Platform "Windows x86"
* Press Build
* NOTICE the build fails.
Expected:
Using Texture2D.alphaIsTransparency should not break a build.
If this is intended to be an editor-only method, consider moving it in to UnityEditor.dll.
Update: This setting is available only in the Editor scripts. Note that changing this setting will have no effect; it must be enabled in TextureImporter instead.

This flag needs to work at runtime to use dynamically-created textures as cursors, otherwise the cursors throw a "Invalid texture used for cursor" warning.

This can also be reproduced on OSX 10.8 and Unity 5.4.0

To be clear, I would prefer to have this functionality available at run time outside of the editor. I cannot guarantee that loaded images will be preprocessed and the alphaIsTransparency apply works much faster than anything I can write in C#.

How else can someone apply alphaIsTransparency to a runtime loaded PNG?
