Replaced the Stackblur algorithm with RenderScripts native blur for better performance. Only issue yet is, that it seems to cause a memory leak.

/**
|
|

* Blur using Java code.
|
|
||||||
*
|
|
||||||
* This is a compromise between Gaussian Blur and Box blur
|
|
||||||
* It creates much better looking blurs than Box Blur, but is
|
|
||||||
* 7x faster than my Gaussian Blur implementation.
|
|
||||||
|
|
||||||
* I called it Stack Blur because this describes best how this
|
|
||||||
* filter works internally: it creates a kind of moving stack
|
|
||||||
* of colors whilst scanning through the image. Thereby it
|
|
||||||
* just has to add one new block of color to the right side
|
|
||||||
* of the stack and remove the leftmost color. The remaining
|
|
||||||
* colors on the topmost layer of the stack are either added on
|
|
||||||
* or reduced by one, depending on if they are on the right or
|
|
||||||
* on the left side of the stack.

* StackBlur v1.0 for Android

|
|
||||||
* Author of the original algorithm: Mario Klingemann <mario.quasimondo.com>
|
|
||||||
* <p/>
|
|
||||||
* This is a compromise between Gaussian Blur and Box blur
|
|
||||||
* It creates much better looking blurs than Box Blur, but is
|
|
||||||
* 7x faster than my Gaussian Blur implementation.
|
|
||||||
* <p/>
|
|
||||||
* I called it Stack Blur because this describes best how this
|
|
||||||
* filter works internally: it creates a kind of moving stack
|
|
||||||
* of colors whilst scanning through the image. Thereby it
|
|
||||||
* just has to add one new block of color to the right side
|
|
||||||
* of the stack and remove the leftmost color. The remaining
|
|
||||||
* colors on the topmost layer of the stack are either added on
|
|
||||||
* or reduced by one, depending on if they are on the right or
|
|
||||||
* on the left side of the stack.
