New debug tool to analyze invalidation performance:

Browse Source 
When fps and debug are activated, also show the mean number of drawn
hexes by frame

If some hexes are invalidated but not drawn (off-screen anims) also
show this number between parenthesis

Also changed "30fps" to "fps: 30" for better readability of these
debug info when around 10
