To activate, use `SetParticleType(int type)`. To deactivate, use `DisableParticle()`.
Types are:
- PT_DEFAULT (default value; uses `gl_particles_style`)
- PT_SQUARE
- PT_ROUND
- PT_SMOOTH
While in this mode:
- `Texture` & `Translation` are ignored
- `Scale.X` sets the size
- `SColor` sets the color
Misc changes:
- Removed warning on textureless destruction
