_glDeleteTextures: delete named textures
- SUB _glDeleteTextures (BYVAL n AS LONG, textures AS _UNSIGNED LONG)
- void _glDeleteTextures(GLsizei n, const GLuint * textures);
- Specifies the number of textures to be deleted.
- Specifies an array of textures to be deleted.
_glDeleteTextures deletes n textures named by the elements of the array textures. After a texture is deleted, it has no contents or dimensionality, and its name is free for reuse (for example by _glGenTextures). If a texture that is currently bound is deleted, the binding reverts to 0 (the default texture).
_glDeleteTextures silently ignores 0's and names that do not correspond to existing textures.
_GL_INVALID_VALUE is generated if n is negative.
