eb3429c6cd Re-enable CPU mipmap generation for Ganesh. Aniso mips were landed a while ago. However, the CPU builder fails when it sees Index8 (among other things), so change the code to fallback to GPU in that case. Additionally, if we're going to be mipping an sRGB image, don't use the CPU code (which is not yet gamma correct). Unfortunately, this means that we will often be using the GPU path, still - with recent codec changes, most images are coming in tagged as sRGB.

ec4d4d784d Change SkTime::GetMSecs to double; ensure values stored in SkMSec do not overflow. 
The following are currently unused in Android, Google3, Chromium, and Mozilla:
  - SkEvent
  - SkTime::GetMSecs
  - SK_TIME_FACTOR (also unused in Skia)
  - SkAutoTime

I left uses of SkMSec more-or-less intact for SkEvent, SkAnimator, and SkInterpolator. SkInterpolator is used in Chromium, so I did not want to change the API. The views/ and animator/ code is crufty, so it didn't seem worthwhile to refactor it. Instead, I added SkEvent::GetMSecsSinceStartup, which is likely to be adequate for use in SampleApp.

I also left SkMSec where it is used to measure a duration rather than a timestamp. With the exception of SkMovie, which is used in Android, all of the uses appear to measure the execution time of a piece of code, which I would hope does not exceed 2^31 milliseconds.

Added skiatest::Timer to support a common idiom in tests where we want to measure the wallclock time in integer milliseconds. (Not used in tests/PathOpsSkpClipTest.cpp because it redefines things in Test.h.)

Removed tabs in tests/StrokerTest.cpp.

397536cabe Consolidate GPU buffer implementations 
Consolidates all the different buffer implementations into a single
GrBuffer class. This will allow us to add new buffer types, use DSA in
OpenGL, track buffer bindings by unique ID, cache buffers without
respect to the type of data they have been used for previously, etc.
This change is strictly a refactor; it introduces no change in
functionality.

a50151dcb5 SkPDF: draw{Image,Bitmap} always serializes early 
Before this change, the PDFCanon held a map from BitmapKeys
to SkImages for de-duping bitmaps.  Even if the PDFDocument
serialized images early, the Canon still held a ref to that
image inside the map.  With this change, the Canon holds a
single map from BitmapKeys to PDFObjects.  Now, Images are
only held by the PDFObject, which the document serializes
and drops early.

This change also:

-   Moves SkBitmapKey into its own header (for possible
    reuse); it now can operate with images as well as
    bitmaps.

-   Creates SkImageBitmap, which wraps a pointer to a bitmap
    or an image and abstracts out some common tasks so that
    drawBitmap and drawImage behave the same.

-   Modifies SkPDFCreateBitmapObject to take and return a
    sk_sp<T>, not a T*.

-   Refactors SkPDFDevice::internalDrawImage to use bitmaps
    or images (via a SkImageBitmap).

-   Turns on pre-serialization of all images.

ff6595286c Turn off Discardable scaled image cache 
This change accidentally slipped into the checked in version of https://codereview.chromium.org/1785643003/ (Switch SkBlurImageFilter over to new onFilterImage interface). It is the reason why we're seeing performance improvements on Android and Ubuntu for the ugamsolutions skp (and others).

I guess the real question is, since it isn't crashing, do we want to leave it enabled?

c429baf7a2 Add getDeferredTextureImageData early out 
Currently, when dealing with deferred texture image data, we will decode the image even if it will later fail to
upload to the GPU due to size constraints.

This change adds an early out to our initial decode /
sizing logic.

3b5bea9d57 Add rowBytesAsPixels and shiftPerPixel to SkPixmap 
This is intended to make it easier to manipulate SkBitmaps and SkPixmaps in a parallel manner (e.g., in https://codereview.chromium.org/1819393002/ (Switch SkMorphologyImageFilter over to new onFilterImage interface))

e8597a4dd0 Delete SkImageDecoder 
This image decoding implementation has been replaced
by SkCodec in Android.

Additionally, we have replaced uses of SkImageDecoder
in Skia and Google3 with uses of SkCodec.

Now we can delete SkImageDecoder :).

1fd50acbaa Sk4x4f: NEON impl. 
Notable tricks:
  - v{ld,st}4q_f32 handle transposing loads and stores of floats in one step
  - vcvtq_n_{f32_u32,u32_f32} let us do conversion to and from floats without shifts
