35 When the active program changes, we need to update it's uniforms.-
36 We could track state for each program and only update stale uniforms-
37 - Could lead to lots of overhead if there's a lot of programs-
38 We could update all the uniforms when the program changes-
39 - Could end up updating lots of uniforms which don't need updating-
40-
41 Updating uniforms should be cheap, so the overhead of updating up-to-date-
42 uniforms should be minimal. It's also less complex.-
43-
44 Things which _may_ cause a different program to be used:-
45 - Change in brush/pen style-
46 - Change in painter opacity-
47 - Change in composition mode-
48-
49 Whenever we set a mode on the shader manager - it needs to tell us if it had-
50 to switch to a different program.-
51-
52 The shader manager should only switch when we tell it to. E.g. if we set a new-
53 brush style and then switch to transparent painter, we only want it to compile-
54 and use the correct program when we really need it.-
