annotate src/timer/SDL_timer_c.h @ 1525:23a347cfbed8

Fixed bug #38 I'm using SDL 1.2.9 with Visual C++ 7.0 on Windows 2000. Here's the setup: my game starts in a window, with SDL_WM_GrabInput(SDL_GRAB_ON) to constrain the cursor to the game window. The mouse cursor is outside of the window when the game launches, and when the window appears the cursor is grabbed and placed at the top left corner of the inside of the game window. At this point, if I click the mouse without moving it, the SDL_MOUSEBUTTONDOWN event's mouse coordinates are (65535,65535).
