Picture just get "blown-up" when I use RoundingParams to get a rounded corner picture

Description

I found an issue that seemed to be caused by RoundingParams, but was actually related to the mTargetDensity of the BitmapDrawable which used in RoundedBitmapDrawable

When the density changed by App-Self, the issue maybe appeared.
e.g. AndroidAutoSize

I want to getting this:

But got this:

Reproduction

Reason

The "blown-up" effect is the result of the updateTransform function：

fresco/drawee/src/main/java/com/facebook/drawee/drawable/RoundedDrawable.java

Line 236 in ba69654

protected void updateTransform() {

Trace the following code：

fresco/drawee/src/main/java/com/facebook/drawee/drawable/RoundedBitmapDrawable.java

Line 45 in 19c695f

super(new BitmapDrawable(res, bitmap));

Bitmap which used in RoundedBitmapDrawable was from this code：

fresco/imagepipeline/src/main/java/com/facebook/imagepipeline/platform/DefaultDecoder.java

Line 276 in ba69654

decodedBitmap = BitmapFactory.decodeStream(inputStream, null, options);

The density of the bitmap which is created in DefaultDecoder is default, but when update transform in RoundedDrawable will use resource density which is changed by App-Self to measure transform

Expected

Now, I solved it, by updating density of bitmap in some custom class, such as DrawableFactory or Postprocessor, but it's probably not safe, I hope to get a formal solution
