Playing HTML shows constant late frames in DIAG window

[pkeuter]

This is because:

The html producer doesnt send frames to caspar if nothing has changed, so the red lines can be misleading if your template is static

Do we need to show these as actual errors, is there a way to distinguish between late frames and no-update-necessary, or should we document this in the new Wiki?

I have had more of a look into this, and I can't see anything we are missing to get more info from CEF. From what I can tell it simply doesnt call OnPaint as it doesnt have anything new for us. Without modding CEF, I don't see a way for us to solve this.

We could improve it a little by changing the colour to something that looks less important and it could be supressed from the trace logging cb39285ffb7ada90c1709ff05b9e10867cd6cc9a

I've raised a PR against CEF to expose the information needed for this https://bitbucket.org/chromiumembedded/cef/pull-requests/179/add-cefrenderhandler-ondidnotproduceframe/diff
