small speedup

Browse Source 
* currentBri() is called for any setpixelColor(), so we can speed up everything (a bit) by allowing the compiler to inline which saves a few cycles of call/return overhead.
* aligned the function with upstream, and added another optimization by only calling progress() when a transition is active.
