RFR: 8319079: Missing range checks in decora [v3]

[Jayathirth D V]

> In SW pipeline path of Box/Gaussian Blur/Shadow effects we are not checking for range when we read data from the source/destination buffers in native code.
> 
> We need to add appropriate range checks in native JNI code also apart from range checks in Java side to make sure that wherever these JNI methods are used we are not performing out of bounds access.

Jayathirth D V has updated the pull request incrementally with two additional commits since the last revision:

 - Update checkRange arguments indentation
 - Add checkRange function comment
