Fixes incorrect scale initialization and inconsistent margins, sets
minimum values for glyph width and height to 1, and labels page 1
more precisely as "Typeface" properties.
This allows for typing [8] instead of [8, 8, 8, 8] to specify the same
margin on all edges, for example. The constructors follow CSS' style of
specifying margins. The added constructors are:
- Margins(int all): Sets the same margin on all edges.
- Margins(int vertical, int horizontal): Sets the first argument to top
and bottom margins, and the second argument to left and right margins.
- Margins(int top, int vertical, int bottom): Sets the first argument to
the top margin, the second argument to the left and right margins,
and the third argument to the bottom margin.
Previously the argument order for Margins was (left, top, right,
bottom). To make it more familiar and closer to how CSS does it, the
argument order is now (top, right, bottom, left).
GlyphBitmap width is currently limited to twiddling 32 bits so
abide by a 32x36 standard for now. Fixes incorrect line values and
ranges and removes unused RefPtr.
