Sam Lantinga 9ff3446f03 Use SDL_bool instead an int return code in the SDL API
Most SDL functions used to indicate success or failure using an int return code. These functions have been changed to return SDL_bool.

Here is a coccinelle patch to change code that previously compared the return value to 0 and changes it to a boolean test:
