Issue description

There seems to be a bug regarding VisualServer that if the input texture has alpha value less than 255 by a given percentage (say 50%) then even if nothing's being done, the (RGB) values of the texture obtained by VisualServer.texture_get_data() would also get decreased by the same percentage (in this case 50%) of their original values

The example project tests the outputs of given colored input images
