1) Don't fracture font glyphs when generating them; we're going
to fracture during triangulation anyway.
2) Don't check for self-intersection when deciding to fracture.
It costs nearly as much as the fracture does.
3) Cache drawing sheet text.
4) Use the current font when checking for cache validity.
5) Parallelize glyph triangulation.
6) Don't invalidate bounding box caches when offset by {0,0}
7) Use the glyph cache when generating text effective shape.
8) Short-circuit NormalizeJustification() if its center/center.
9) Don't triangulate for GuessSelectionCandidates()
10) Avoid sqrt whenever possible.
11) Pre-allocate bezier and SHAPE_LINE_CHAIN buffers.

Since the format has been changed to RGBA8, default (UN)PACK_ALIGNMENT = 4
works correctly, so the texture width padding to 4 is not needed anymore.

The disable grid hotkey should allow the snap scale to be completely
determined by the snapSize and world scale. This prevents snapRange
from overriding in the case where grid is disabled.
Additionally, we disallow grid snapping when the grid scale is not
visible. This means that when zoomed out sufficiently to not show the
minor ticks, these minor ticks will not override a snap

Rather than not drawing, which will miss some imported elements that
should be visible due to the line width, we draw a zero-length line that
appears as a point.
It was re-enabled by commit cbc3bfbf.
The current code to handle cached bitmaps is no longer compatible with the
current code.
Many cached items are created because a lot of clones are used to manage bitmap images.
Cached items are never cleaned, so a lot of memory is never freed after
using these temporary clones
And caching items do not significantly speedup drawings.
Also adjusts metrics to better match stroke font.
Also removes text-halo highlighting as it's too expensive to re-render
when the zoom changes.
