Do checks before adding an attachment. Fixes #19
Step Masonry Image width by 1

Stepping by 10 really limits the ability of galleries to fill the post
content area fully.
Disable image transitions to avoid flash

Transitions force the full image to flash during the transition, so it's
best to simple disable them. Site's that apply a css transition on hover
over images (like our docs site does), will see the square image flash
on the circular style. This pre-emptively disables that.
Force line-height

Force line-height to ensure proper spacing below images. Some themes
apply line-height: 1.5 to divs or a elements for readability.  Forcing
this to "0" resets the line-height completely so the spacing is
controlled 100% by the padding applied through the template settings.
Font-size: 0 for vertical reset

Adding font-size: 0 ensures the gap reset works for both horizontal and
vertical spacing. Thanks to bradvin for that.
