False by default, which is the norm for PNG images. Set to true if the RGB values have
been stored premultiplied by alpha.
If set to *true*, the alpha channel, if present, is multiplied into the color channels when the texture is uploaded to the GPU. Defaut is *false*.<br/><br/>
Note that this property has no effect for [link:https://developer.mozilla.org/de/docs/Web/API/ImageBitmap ImageBitmap].
You need to configure on bitmap creation instead. See [page:ImageBitmapLoader].

<h3>[property:boolean flipY]</h3>

True by default. Flips the image's Y axis to match the WebGL texture coordinate space.
