dtourolle 1985163827 fix(functional): form field labels no longer overprint the field above (S15) ...

FormFieldText treats its origin as the control's top-left - size and in_object
both measure down from it - but drew the label by calling Text.render at that
origin, and Text anchors on the baseline. The label's glyphs therefore landed
above the origin, outside the box the control claims, on top of whatever was
there. In a stacked form that is the preceding field's input box, which is what
example_10_forms.png showed: every label but the first crowding the box above it.

The label is now offset down by its ascent, so it occupies the space the control
accounts for. Height derives from the label's ink height rather than the nominal
font size, which had also eaten into the 5px gap between label and box.

LABEL_GAP names that gap and field_area_offset gives the distance from the origin
to the top of the input box; render, handle_click and the height calculation now
share it instead of each recomputing font_size + 5.

Also recorded under S12: the broken process pool is not merely wasted work. It
forks from a process that already has threads, and
tests/layout/test_ereader_image_rendering.py hangs at interpreter exit roughly
one run in four - every test passes, then the process never returns.
