'''gl.CreateFBO'''
( [ table initialization ] ) -> userdata [[Lua_FBO#Userdata_FBO|fbo]]

initialization table can contain:

attachment ::= luaTex or RBO or nil or { luaTex [, num [[Lua_ConstGL#FBO_Targets|target]] [, num level ] ] }

{
depth = attachment,
stencil = attachment,
color0 = attachment,
color1 = attachment,
color2 = attachment,
..
color15 = attachment,
drawbuffers = { GL_COLOR_ATTACHMENT0_EXT, GL_COLOR_ATTACHMENT3_EXT, ..}
}


'''gl.DeleteFBO''' (This doesn't delete the attached objects!)
( fbo ) -> nil

'''gl.IsValidFBO'''
( fbo [, number [[Lua_ConstGL#FBO_Targets|target]] ] ) -> boolean valid [, number [[Lua_ConstGL#FBO_Status|status]] ]

'''gl.ActiveFBO'''
( fbo [, number [[Lua_ConstGL#FBO_Targets|target]] ] [, boolean identities ] , lua_function, arg1, arg2, ... ) -> nil

'''gl.UnsafeSetFBO''' (Binds a FBO like gl.ActiveFBO() does, but you have to unbind it yourself!)
( nil [, number [[Lua_ConstGL#FBO_Targets|target]] = GL_FRAMEBUFFER_EXT ] ) -> nil (Bind default screenbuffer)
( fbo [, number [[Lua_ConstGL#FBO_Targets|target]] = fbo.target ] ) -> nil

'''gl.RawBindFBO''' (Replaces UnsafeSetFBO starting from 104.0.1-1003-gb3e02a6 maintenance)
( nil [, number [[Lua_ConstGL#FBO_Targets|target]] = GL_FRAMEBUFFER_EXT ] [, number rawFboId = 0] ) -> nil (Bind default or specified via rawFboId numeric id of FBO)
( fbo [, number [[Lua_ConstGL#FBO_Targets|target]] = fbo.target ] ) -> number previouslyBoundRawFboId

'''gl.BlitFBO''' needs GLEW_EXT_framebuffer_blit
( int x0Src,y0Src,x1Src,y1Src,
int x0Dst,y0Dst,x1Dst,y1Dst
[, number mask = [[Lua_ConstGL#Clear_Bits|GL_COLOR_BUFFER_BIT]] [, number filter = GL_NEAREST ] ] ) -> nil

( fboSrc , int x0Src,y0Src,x1Src,y1Src,
fboDst , int x0Dst,y0Dst,x1Dst,y1Dst
[, number mask = [[Lua_ConstGL#Clear_Bits|GL_COLOR_BUFFER_BIT]] [, number filter = GL_NEAREST ] ] ) -> nil

===Userdata FBO===
attachment ::= luaTex or RBO or nil or { luaTex or RBO [, num [[Lua_ConstGL#FBO_Targets|target]] [, num level ]] }

write-only methods are:
'''fbo.depth''' = attachment
'''fbo.stencil''' = attachment
'''fbo.color0''' = attachment
..
'''fbo.color15''' = attachment
'''fbo.drawbuffers''' = { GL_COLOR_ATTACHMENT0_EXT, GL_COLOR_ATTACHMENT3_EXT, ..}
'''fbo.readbuffer''' = GL_COLOR_ATTACHMENT0_EXT

==RBO==
'''gl.CreateRBO'''
( int xsize, int ysize,
[ {
target = GL_RENDERBUFFER_EXT,
format = [[Lua_ConstGL#RBO_Formats|GL_RGBA]],
[samples = number], any number here will result in creation of multisampled RBO (Added in 104.0.1-1015-g8e36ef2 maintenance)
} ]) -> userdata [[Lua_FBO#Userdata_RBO|rbo]]

'''gl.DeleteRBO'''
( rbo ) -> nil

===Userdata RBO===
read-only methods are:
'''rbo.target''' = number
'''rbo.format''' = [[Lua_ConstGL#RBO_Formats|number]]
'''rbo.xsize''' = number
'''rbo.ysize''' = number
'''rbo.valid''' = boolean
'''rbo.samples''' = number will return globalRendering->msaaLevel for multisampled RBO or 0 otherwise (Added in 104.0.1-1015-g8e36ef2 maintenance)
