// NOTE: the official SDL distribution has two problems on Windows:

|
// multiple heaps are active; errors result when allocated blocks are
|
|
// (for reasons unknown) passed to a different heap to be freed.

|
// one workaround is to add "/nodefaultlib:msvcrt.lib" to the linker
|
|
// command line in debug configurations.

// cursor.cpp's efforts by resetting the mouse cursor after movement.
