More general fix for bug #189 The clipping is done at a higher level, and the low level functions are passed clipped rectangles. Drivers which don't support source clipping have not been changed, so the image will be squished instead of clipped, but at least they will no longer crash when the destination rect was out of bounds.

SDL_CDOpen\- Opens a CD-ROM drive for access\&.
.SH "SYNOPSIS"
.PP

\fBSDL_CD *\fBSDL_CDOpen\fP\fR(\fBint drive\fR);
.SH "DESCRIPTION"
.PP
Opens a CD-ROM drive for access\&. It returns a \fI\fBSDL_CD\fR\fR structure on success, or \fBNULL\fP if the drive was invalid or busy\&. This newly opened CD-ROM becomes the default CD used when other CD functions are passed a \fBNULL\fP CD-ROM handle\&. 
.PP
Drives are numbered starting with 0\&. Drive 0 is the system default CD-ROM\&.
