Removed simple tests steps from CanvasTest.

CanvasTest only checks if the state of the different canvas
implementations are consistent with the one of the default
implementation.

Because most of the draw calls are stateless and already tested in GMs
the test steps that exercices them are not useful.

Allocate only the vertices we need for text.

This restructures the vertex allocation for text rendering to compute
the max number of vertices we would need for a line of text, and then
only allocate that much. If this number exceeds the quad index limit,
then it will allocate for the max number of quads, and reallocate for
the rest later.

Correct typo in SkRemotableFontMgr_win_dw.cpp.

New code was introduced behind a flag, but in that code there is a comma
before a parameter name instead of after.
