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