Detailed Description

Here is how the get/set macros are used.

First note there are 4 types of access: for each of get and set we can do it with or without bounds/cache checking. These are respectively defined in 4 macros: GET_PIXEL SET_PIXEL FGET_PIXEL FSET_PIXEL (fast get...) Arguments for GET_PIXEL and FGET_PIXEL are (x,y) (i.e. column,row) and they return the value. For SET_PIXEL FSET_PIXEL, the syntax is SET_PIXEL(x,y,value). Note that SET_PIXEL is expected to return value! We support operator() being the access, or if the used defines USE_NAMED_ACCESSORS, the named accessors. For the named accessors the user can define the names to use. (And if they really want to, they can change the defines for GET_PIXEL SET_PIXEL... but be careful as existing code uses the args in the given order.)
