Hey @aeisenbarth, many thanks for your suggestion and the code contribution! I have copied it over to #192 so that I can easily add the corresponding tests. So I'll be closing this here. |

When issueing multiple render commands of the same type, only the last command is executed. Multiple same rendering commands can be desired when blending different images (with alpha != 1) or creating a collage of images at different spatial locations.
This is caused by storing parameters in an ordered dictionary with the command type as key. Instead, onecould directly use a sequence of tuples.
