Native cursors for GameMaker

This extension provides the ability to set system-level cursors for the game' window. Such cursors are framerate-independent.

Included functions:

• window_set_cursor_sprite(sprite, subimg)
• window_set_cursor_sprite_ext(sprite, subimg, xscale, yscale, blend, alpha)
• window_set_cursor_surface(surface, hotpoint_x, hotpoint_y)
• window_set_cursor_surface_part(surface, hotpoint_x, hotpoint_y)
• window_set_cursor_normal() (reverts to cursor set via built-in functions)

Supported platforms:

• Windows: via DLL (WndProc hook).
  Supports cursors up to 256x256px.
  Likely works on UWP/Windows Store native apps, but wasn't tested yet.
• HTML5: via JS (CSS3 cursors).
  Supports cursors up to 128x128px.
  On WebGL, cursors can only be changed in draw event, since drawing operations do not work elsewhere.
• Given demand, Mac and Linux will be supported in future.

Package contains:

• The extension itself.
• Sample project (shown on the GIF).
• Source code (GML and native extensions).

Artwork pending.
