41 When the active program changes, we need to update it's uniforms.-
42 We could track state for each program and only update stale uniforms-
43 - Could lead to lots of overhead if there's a lot of programs-
44 We could update all the uniforms when the program changes-
45 - Could end up updating lots of uniforms which don't need updating-
46-
47 Updating uniforms should be cheap, so the overhead of updating up-to-date-
48 uniforms should be minimal. It's also less complex.-
49-
50 Things which _may_ cause a different program to be used:-
51 - Change in brush/pen style-
52 - Change in painter opacity-
53 - Change in composition mode-
54-
55 Whenever we set a mode on the shader manager - it needs to tell us if it had-
56 to switch to a different program.-
57-
58 The shader manager should only switch when we tell it to. E.g. if we set a new-
59 brush style and then switch to transparent painter, we only want it to compile-
60 and use the correct program when we really need it.-
