Fixed bug #901

Disable mouse event generation when state is not SDL_APPMOUSEFOCUS
If a Windows SDL application is minimised by using alt-tab, SDL_APPMOUSEFOCUS
is lost as part of the minimisation. Unfortunately, the directx driver doesn't
pay any attention to this state when generating mouse button events, so
clicking on the Desktop can cause mouse clicks in the SDL application, while
it's still minimised. The attached patch fixes this. It looks much more
complicated than it actually is due to indentation; here it is ignoring
whitespace:

| 23 .fi | |
| 24 .PP | |
| 25 .PP | |
| 26 If the drive has a CD in it, the table of contents of the CD and current play position of the CD will be stored in the SDL_CD structure\&. | |
| 27 .PP | |
| 28 The macro \fBCD_INDRIVE\fP is provided for convenience, and given a status returns true if there\&'s a disk in the drive\&. | |
