38f104e85d combine direct position calculation
Make the glyph buffers use the same Direct position calculations
for Bitmap and GPU processing. This will create fewer changes when
switching to SkGlyphDigest based API.

6c630f2ce6 Make SkScalerContext enums scoped.
This was motivated by SkScalerContextFlags putting `kNone` into the
global namespace. Instead of adding a suffix, change these internal
enums to be scoped and update the users.

Because SkScalerContextFlags is used like a bitfield,
`SK_MAKE_BITFIELD_OPS` is used to provide the appropriate operators. The
macro implementation is updated to handle scoped enums, remove the very
dangerous, unwanted, and unused templated operators, and add operator~
since that is needed by one existing user.

Also, for some reason this allows the compiler to find an unused field
which is removed.

bee5ccd548 Avoid "drawable" when not referring to SkDrawable.
Change all use of "drawable" to "accepted" in glyph drawing code. To
improve uniformity "rejects" is also changed to "rejected".  This is
motivated by the desire to add SkDrawable backed glyph rendering, which
would make the use of "drawable" for both "glyphs which are drawable"
and "glyph which renders with SkDrawable" very confusing.

30fdea3d8f track glyph scaling hints in min/max pairs
Track the scaling hints as the minimum of the maximum dimension and
the maximum of the maximum dimension. Having the range will allow
for better scaling choices in the drawing of last resort.

The next CL will start using this range to calculate scaling factors.

79c5674a4c Place transformed drawing data at source space (0,0)
The direct device remains fully positioned,
and will be addressed in a following CL.

This is a step towards making the vertex data
constant. The path data is positioned at draw
time instead of at creation time.

The GPU data is not constant at this time, but
when all the vertex data is placed at (0,0) the
data can be const.
