The texture 51buffer object is used as vertex array, index array, vertex texture and fragment 52texture. Rendering using the texture buffer object simultaneously in different 53ways is also tested. 54 55Modifying tests create a texture buffer object, modify it and render it to the 56default framebuffer using it as fragment texture. 57 58Modify render tests will create texture buffer object, modify it and render it 59to the default framebuffer. 60 61Render modify tests will create a tests buffer object render it to default 62framebuffer, modify it and render it again to default framebuffer as fragment 63texture. 64 65All textures use RGBA8 format and buffer data is always used as unsigned bytes. 66Used values for bytes are also limited to simplify verification. Verification 67is always performed at the end of the test. 68
