Update markdown to use absolute image paths, fixing broken images

Markdown can be served with or without a trailing slash but when a
trailing slash is present, relative image links were broken.

The following example works as expected:
url: https://skia.org/dev/design/pdftheory
image url: PdfLogicalDocumentStructure.png
resolves to: https://skia.org/dev/design/PdfLogicalDocumentStructure.png

The following example was broken before this patch:
url: https://skia.org/dev/design/pdftheory/
image url: PdfLogicalDocumentStructure.png
resolves to: https://skia.org/dev/design/pdftheory/PdfLogicalDocumentStructure.png

The PdfLogicalDocumentStructure.png file lives in /dev/design/, not
/dev/design/pdftheory/. This patch updates all images in our markdown
files to be served with the full path so a trailing slash no longer
breaks images.

Move sRGB <-> linear conversion components to their own files.

This makes them a little easier to use outside SkColorXform code.

I've added some notes about how best to use them and their eccentricities, and added a test.

Ultimately any software sRGB <-> linear conversion should funnel somehow through here.

Begin instanced rendering for simple shapes

Adds a module that performs instanced rendering and starts using it
for a select subset of draws on Mac GL platforms. The instance
processor can currently handle rects, ovals, round rects, and double
round rects. It can generalize shapes as round rects in order to
improve batching. The instance processor also employs new drawing
algorithms, irrespective of instanced rendering, that improve GPU-side
performance (e.g. sample mask, different triangle layouts, etc.).

This change only scratches the surface of instanced rendering. The
majority of draws still only have one instance. Future work may
include:

 * Passing coord transforms through the texel buffer.
 * Sending FP uniforms through instanced vertex attribs.
 * Using instanced rendering for more draws (stencil writes,
   drawAtlas, etc.).
 * Adding more shapes to the instance processor’s repertoire.
 * Batching draws that have mismatched scissors (analyzing draw
   bounds, inserting clip planes, etc.).
 * Bindless textures.
 * Uber shaders.

Fix caching of sample locations

The original caching logic for sample locations wishfully assumed that
the GPU would always use the same sample pattern for render targets
that had the same number of samples. It turns out we can't rely on
that. This change improves the caching logic to handle mismatched
simple patterns with the same count, and adds a unit test that
emulates different sample patterns observed on real hardware.

Revert of Increase batching for AA fill rects. (patchset #4 id:60001 of https://codereview.chromium.org/2116823002/ )

Reason for revert:
I believe this is causing the Chromium DEPS roll to fail due to linux_blink_rel. Reverting for now to get the roll going again.

Begin instanced rendering for simple shapes

Adds a module that performs instanced rendering and starts using it
for a select subset of draws on Mac GL platforms. The instance
processor can currently handle rects, ovals, round rects, and double
round rects. It can generalize shapes as round rects in order to
improve batching. The instance processor also employs new drawing
algorithms, irrespective of instanced rendering, that improve GPU-side
performance (e.g. sample mask, different triangle layouts, etc.).

This change only scratches the surface of instanced rendering. The
majority of draws still only have one instance. Future work may
include:

 * Passing coord transforms through the texel buffer.
 * Sending FP uniforms through instanced vertex attribs.
 * Using instanced rendering for more draws (stencil writes,
   drawAtlas, etc.).
 * Adding more shapes to the instance processor’s repertoire.
 * Batching draws that have mismatched scissors (analyzing draw
   bounds, inserting clip planes, etc.).
 * Bindless textures.
 * Uber shaders.
