How online / live are different?

[Ivan Korotkov, 2012/06/09 14:19:01]

.online means that camera is working (i.e. present and initialized)
.live means that camera is in live mode (shown to user); when user takes a
picture, streaming is not stopped (camera remains .online but no longer .live
and is hidden)

+ * .camera: camera (live or photo) is selected;
+ * .live: camera is in live mode (no photo taken yet/last photo removed).

Please make sure that doesn't affect existing layout (with new camera being
disabled).

[Ivan Korotkov, 2012/06/09 14:19:01]

Done.

Btw, why w-h is 220x220 when we capture 160x160?

nit: May as well add separate style that defines display: none; with old camera
type. Looks easier to cleanup.

[Ivan Korotkov, 2012/06/09 14:19:01]

It should already be display: none in base style (so that it's only shown camera
is live), why add another style for old type?

No need in RTL support as this is symmetric (left == right)

nit: Same here, makes sense to define "display: none;" as a part of old camera
type rule.

[Ivan Korotkov, 2012/06/09 14:19:01]

Same reasoning
