1146508 - Fit entire viewport onto screen on page load

Status: RESOLVED WORKSFORME

(Core :: Panning and Zooming, defect)

Description

[Botond Ballo [:botond]]

This was originally filed as bug 1068871.

In that bug, we did part of the work: we adjusted the minimum zoom to allow fitting the entire page onto the screen, subject to the global minimum zoom amount.

Note that in particular, that change should allow fitting the entire viewport onto the screen (potentially modulo some pathological cases where the viewport is set to be so larger that it doesn't fit onto the screen at the global minimum zoom).

The rest of the work is to change the initial zoom to be such that the viewport fits onto the screen.

I intend to make this a mentored bug after bug 1068871 is fixed.

I tested this on Fennec both with and without APZ, and the desired behaviour is already in place (see bug 1068871 comment 64). I haven't tested the behaviour on B2G, but as we no longer care about that, I'm going close this bug as WORKSFORME.
