  - Rewrite the names to be less mysterious looking.  No more Xs.

  - Make the src type uniformly const void*, to allow for 888 (RGB) srcs.

This should be performance and pixel neutral.  (Please revert if it's not.)

Fix CMake build on Mac.

Stop testing builds with runtime-detected NEON

O frabjous day!

Chrome has switched on requiring NEON globally at head.
Android has always built with NEON as appropriate for each device.

In practice, this switches our Nexus 5 bots from runtime-detected to
building with NEON globally.  It also lines a few columns up and makes
equivalent aliases more obviously the same.

We still have Build bots to test we can build on ARMv7 with no NEON.  (We even have Build bots to test building ARMv6.)

(It looks like that buildbot_spec.json just hasn't been updated in a while.)

remove fragile assert

The assert basically wants the following to always be true (but it aint)

floor(int + 0.5 + float) == floor(0.5 + float) + int

... where int + 0.5 happens first, and then we add the float.

Review URL: https://codereview.chromium.org/1521633002

Texturing support for RECTANGLE textures.

Uses textureSize() to unnormalize texture coords when reading from a RECTANGLE texture. Because of this we also require a later GLSL version to use rectangle textures (1.40).

Note that this causes a issue with the bicubic effect. The texture coords seem to have poor precision and the result is ugly. textureSize() is intended as a workaround until effects can be updated to handle unnormalized coords themselves.

Updates places where we were looking for OpenGL version 3.2 for rectangle support. It was actually added in 3.1.
