Alignment on paint for actual glyph drawing needs to always be left,
even when drawing centered or right aligned text. The x offset for
alignment is applied by OpenGLRenderer::drawText (and needs to be early
in the pipeline for quickReject to work). Similar change needed for
drawing drop shadow.
Also fixes bug with mispositioned underline (offset for alignment has
already been applied once, no need to do it again in
drawTextDecorations).

This patch adds support for drop shadows (setShadowLayer) for
drawPosText in the hwui renderer. In and of itself, it's not very
important, but it's on the critical path for correct mark positioning,
tracked as bug 5443796.
The change itself is fairly straightforward - it basically just adds an
extra "positions" argument to all draw and measure methods on the code
path for drawing drop shadowed text, as well as to the cache key for
cached shadow textures.

This change sets textures filtering to GL_NEAREST by default. GL_LINEAR
filtering is only used when textures are transformed with a scale or
a rotation. This helps save a couple of fps on some GPUs.
