Class Texture

src/main/java/field/graphics/Texture.java:47–1083

An OpenGL texture. Handles async double-buffered PBO texture upload by default. Follows the same pattern as FBO --- create a texture by picking one of the growing number of static helpers in TextureSpecification that mask the complexity of OpenGL enums
