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