double click didnt check mouse distance moved so you could click twice in different areas of the screen very fast and generate a double click event which had old mouse coords copied into it but was sent to an operator set to run on single click (because the double click wasnt handled). Also added MEM_name_ptr function (included in debug mode only), prints the name of allocated memory. used for debugging where events came from.

* @section about About the MEM module
|
|
*
|
|
* MEM provides guarded malloc/calloc calls. All memory is enclosed by
|
|
* pads, to detect out-of-bound writes. All blocks are placed in a
|
|
* linked list, so they remain reachable at all times. There is no
|
|
* back-up in case the linked-list related data is lost.
|
|
*
|
|
* @section issues Known issues with MEM
|
|
*
|
|
* There are currently no known issues with MEM. Note that there is a
|
|
* second intern/ module with MEM_ prefix, for use in c++.
|
|
*
