|
* Simple fake tilt-shift effect, modulating two pass Gaussian blur (see above) by vertical position
|
|
*
|
|
* - 9 samples per pass
|
|
* - standard deviation 2.7
|
|
* - "h" and "v" parameters should be set to "1 / width" and "1 / height"
|
|
* - "r" parameter control where "focused" horizontal line lies
