Subject: [PATCH] Fix incorrect hotspot calculation for cursor positioning

Corrected the calculation of the vertical hotspot position in the `GetCachedCursor` function.

Changed the variable from `data->hot_x` to `data->hot_y` to ensure the correct vertical position of the cursor's hotspot is used when scaling.
