9-patch graphics for bubble do not scale correctly on XXHDPI devices about android-maps-utils

If it helps, I can submit a pull request with my suggested fix for this.

The cause of this issue is that image scaled from xhdpi to xxhdpi is resized 1.5 times and it may happen one of the stretched pixel columns is replicated and the other is not.
While your solution is ok, it will cause all parts of the image (paddings, upside-down caret, rounded corners) appear bigger on devices with lower densities and smaller on extra, extra (extra and in the future probably one more extra ;)) high density screens. Over 5 times bigger on ldpi compared to xxxhdpi.
A more appropriate way would be to duplicate stretched region's pixels 8 times for xhdpi, so when it is scaled to xxhdpi, it will always be 12 pixels on both regions and when scaled down to ldpi - 3 pixels.
Just a suggestion.
