Proposal Improvement of Transport Toolbar

The Problem
The current GUI for the Recording indicator on the Transport Toolbar is nowhere near as clear as it could be. When recording is inactive the button is displayed "raised" and in a fairly dull red color, clearly indicating an off state, When the user presses the record button to activate the recording the button changes to the "depressed" display but remains the same dull red color.

Proposed Feature
The user should be given useful visual cues indicating the three recording states:
 * 1) actively-recording,
 * 2) armed/paused,
 * 3) inactive.

Developer/QA Backing

 * Peter +1 for glowing-red button (and -1 for flashing red button)
 * Koz

Use Cases
Not applicable

Active Recording
When actively recording, the button should change color to a much brighter red, a "glowing" red to emulate an LED that is "on" and show "depressed". The much brighter glowing red would more clearly indicate an "on" or "active" state

The fading smudgy red outside the circular button icon is deliberate and is designed to look like an LED light that is glowing "on".

When this was discussed on the Forum there was an alternative suggestion that the button should change to bright red and blinking (and depressed) to indicate the "active" recording state, but I believe that this would be viually distracting.

Armed state
When the recording is armed but not recording (click Pause then click Record - or just paused while recording) the record button should be displayed as: depressed, standard red, i.e as it currently appears while either armed or actively recording. The Pause button also displays depressed, as now.

Recording inactive
When recording is inactive the record button should display as now.
