Log Message

  • Added glGetError() checks after every GL call (its ugly, I know, but it helps with debugging). Added option to disable it with constant on RendererUtil.ENABLE_ERROR_CHECKING.
  • Set lastFb in OGLESShaderRenderer when context is reset, this is needed otherwise the state tracker would not work correctly.
  • Fix issue with Mesh.Mode.Hybrid that wasn't rendering triangle fans correctly (was rendering them as triangle strips instead).
  • Remove call to glPointSize in OGLESShaderRenderer (it would most likely crash anyway, since GLES10 calls can't be used in a GLES20 context)
  • TestCustomMesh now uses shorts instead of ints for the index buffer. 32-bit indices are not supported on Android and are slower on Desktop, don't use them if you can avoid it.
