Description
There is 48% (16.70 fps) performance regression in GUIMark2.Bitmap in MacOS in build 8.0-graphics-scrum-h242.
The results on Mac-Mid-Range machine are:
 h241: 34 fps
 h242: 17 fps 

According to Hudson the build 8.0-graphics-scrum-h242 contains the following changes:
 1. Fix RT-24566: Resolve semantics of texture padding.
    Many other effect and ImagePattern bugs on embedded are likely resolved with this fix as well.
 2. Fix RT-24566: Resolve semantics of texture padding.


The regression is easy reproduced. Steps to run the benchmark:
> cd JFX_WS/tests/performance/GUIMark2/
> ant
> java -Djavafx.animation.fullspeed=true
       -cp "JFX_HOME/rt/lib/jfxrt.jar;./dist/GUIMark2.jar"

I have created JPA profiles for builds b241 and b242 on Mac-Low-End machine. The fps numbers I got are 41.3 and 21.3 correspondingly. According to JPA profiles the time spent in NGImageView.doRender to render 10 pulses has been increased from 187 ms to 411 ms. This is mostly attributed by time increase spent in BaseShaderContext.setTexture (from 180 ms to 313 ms).
