Panel Design and Function Matching

[WatchMkr]

This issue outlines remaining changes to match the design.

Design issue
Figma file

• Auto-hiding panel current leaves a couple pixels visible. The panel should hide entirely.
• Revealing the auto-hidden panel should cover windows instead of moving them when tiling is enabled (works in floating mode)
• Use 8px corner radius when the panel is floating (gap enabled)
• Contracted panel (not extended) and disabled gap should contract the panel background (currently only contracts content)
• When the panel is contracted and gap is disabled, use 8px corner radius for the two corners not adjacent to the screen edge
• Clicking from one applet to the next often doesn't work the first time requiring a second click

In the Figma file "Components" page, active applet icons use the accent color. I haven't seen this in prototypes but it's a cool idea. Is this possible with the work @mmstick has done recently for accent color in window headers?

• Can not reveal auto-hidden panel when a window is maximized (tested with cosmic-settings)

This issue is with cosmic-settings not cosmic-panels. Created an issue in cosmic-settings to track. Closing this issue.
