[PATCH] wined3d: Always try to create a hardware cursor.

[Stefan Dösinger]

If my memory of my own experiments are right then what your patch does is correct for windowed mode. In Windowed mode native d3d9 never renders an SW cursor and instead creates a scaled HW cursor.

In fullscreen mode I do get a (non-moving by default) SW cursor for a 64x64 texture, or at least used to when I tested it on Windows 7 years ago. The behavior might have changed. Since comment 7 on bug 47386 indicates that the game calls SetCursorProperties over and over it might be the correct thing to update the cursor position to the current user32 cursor pos in SetCursorProperties.

How does the cursor appear on Windows? Does it look like a 32x32 or 64x64 cursor? Also keep in mind the possibility that the cursor is a 64x64 one where only a 32x32 part of the texture contains non-transparent data.
