If the developer gives some weight/italic to the Typeface.Builder
the fallback used the metadata in the font file. We should use
provided data instead.
This CL also adjusts upper and lower limits on weight, from 100..900 to
1..1000

setFallbackTypeface is returned by Builder.build() method when the
provided font is not loaded due to some reasons.
The fallback family is resolved with width/italic passed to Builder.

Implement missing color management pieces for bitmaps:
- Bitmap.createBitmap(Bitmap src, ...) now creates a bitmap
in the same color space as the source bitmap
- Bitmap.createScaledBitmap() now creates a bitmap in the
same color space as the source bitmap
- Bitmap.createBitmap(..., ColorSpace colorSpace) to create
bitmaps in a specific color space
- Fix copy from A8 to F16
- Copying bitmaps in F16 or with a color space does not work,
it's currently a limitation in Skia

Fix a bug in DrawShadow matrix calculation. Recorded matrix does

This is fixed in Skia by passing the appropriate flag when the shader is
generated. The fix in HWUI is to reverse the premultiplication and
interpolation steps.

libplatformprotos is really really unhappy if it gets
loaded twice into the same process which trivially happens
if it's a static library. Switch it to a shared library
instead to fix this.

Test: Ran hwui_unit_test, didn't crash
This change also fixes an issue with RGBA16F bitmaps when modulated
with a color (for instance by setting an alpha on the Paint object).
The color space conversion is currently done entirely in the shader,
by doing these operations in order:
1. Sample the texture
2. Un-premultiply alpha
3. Apply the EOTF
4. Multiply by the 3x3 color space matrix
5. Apply the OETF
6. Premultiply alpha
Optimizations:
- Steps 2 & 6 are skipped for opaque (common) bitmaps
- Step 3 is skipped when the color space's EOTF is close
to sRGB (Display P3 for instance). Instead, we use
a hardware sRGB fetch (when the GPU supports it)
- When step 3 is necessary, we use one of four standard
EOTF implementations, to save cycles when possible:
+ Linear (doesn't do anything)
+ Full parametric (ICC parametric curve type 4 as defined
in ICC.1:2004-10, section 10.15)
+ Limited parametric (ICC parametric curve type 3)
+ Gamma (ICC parametric curve type 0)
Color space conversion could be done using texture samplers
instead, for instance 3D LUTs, with or without transfer
functions baked in, or 1D LUTs for transfer functions. This
would result in dependent texture fetches which may or may
not be an advantage over an ALU based implementation. The
current solution favor the use of ALUs to save precious
bandwidth.

Skia would like to move SkOSFile and make it private spi. This appears
to be the only place SkOSFile is used outside Skia, and using access
here directly is more apropriate.

Frankengradients (linearly interpolated RGB, gamma interpolated alpha) look
fantastic but unfortunately create sligh compatibility issues. For instance,
a gradient from 0xffea1030 to 0x00ea1030 (opaque to alpha, with a single
color) blended on top of 0xff101010 would not look the same as a single
opaque gradient from 0xffea1030 to 0xff101010. The difference is hardly
noticeable on simple gradients but it could cause confusion amongst app
developers. Their life is hard enough as it is, let's be good to them.
My crusade against the gamma world is not over and one day I shall
be the victor. I am patience.

If the path had an inverse fill type we were incorrectly
converting ovals and roundRects to their primitive form
without checking to ensure the path was not inverse fill.

Here we have SurfaceView bypass the WindowManager and speak
directly to SurfaceFlinger using child surfaces. We also
implement some logic in the WM to handle child surfaces
in various Surface replacement scenarios.
For those following along in the revert Saga, this
also includes the follow up CLs to the original CL.
- Surface inset calculation
- Animation fixes.
The error causing the revert was an incorrect JNI signature
around deferTransactionUntilSurface. I've noted it inline.
