LayoutLib: Misc rendering fixes.
- always set up the stroke. Paint may not have the proper
style when drawing lines. stroke should still be setup.
- Fixed vertical linear gradient. Old code generated
a gradient ratio of NaN
- Fixed alpha rendering when using shaders. In that
case the alpha channel from the paint color should be
used in conjunction with the shader.
- Fixed miter limit. Java expects the value to be multiplied
by the stroke width
- Fixed support for drawing ALPHA_8 bitmaps. Java2D doesn't
have bitmaps with only alpha channels, so we keep using
ARGB bitmaps but when drawing them into a bitmap we erase
the color information.
