wxGetCursor Implementation

wxGetCursor Implementation Suggestion

[vadz]

Thanks for the PR, but this will break linking under non-MSW platforms, the function should be at least implemented as returning wxNullCursor there, although, unless there is a possibility of getting the current cursor on a platform other than MSW, I'm not sure if it's really useful to have it at all.

Any new function also needs to be documented in interface/wx/utils.h.

I'll add the additional functions for the other platforms. Then, we can go from there.

Added the additional functions which were required for each platform.
Removed two function declarations which were already defined in in the gdicmn.h

Adding implementations for the various platforms.
Also, in regards to your comment about its usefulness, I would agree that in most cases it isn't useful, so if you want to remove this PR, thats fine. I just saw that there was a missing Getter...

[smasherprog]

Added other implenetations, but I cannot verify if they are correct because I dont have the platforms. I have completed all that I can for this PR. Let me know if you need additional changes.

Did you close it because you found some problem with it or for some other reason?
