Textures

The following functions are all related to "textures", i.e.: images that are stored in VRAM to be used as sprites or other graphical elements within your game.

Textures refer to: 

• Texture Pages created by GameMaker, which contain: 
  • Sprites that you add to Texture Groups or place on a Separate Texture Page
  • Font glyphs
  • Tile Sets
• Surfaces: custom textures that provide a canvas that you can draw anything to
