76b15e895a [MATERIALS BREAK] higher period clock 
THIS CHANGE BREAKS MATERIALS.

This adds getUserTime() in shaders/materials, which returns the time
in second since Renderer::resetUserTime() was called.
Two values are provided, the time in second encoded as a float and
the difference between that and the double value, which together allows
to perform high precision time computation when needed.

This change allows longer running animations in materials. Using only
the float value, give millisecond resolution for more than 4h.

beaf751604 filamesh: Compress attributes individually. 
This further reduces compressed suzanne from 333489 bytes to 272761.

Tested with vk_hellopbr and tutorial_suzanne.html

9915ec7841 EV100 formula typo (#543)

78804251e9 Corrected typo in formula (#519) 
It looks like there is a minus sign missing in there, see https://www.wolframalpha.com/input/?i=(((1%2Bsqrt(x))+%2F+(1+-+sqrt(x)))+-+1.5)+%2F+(((1%2Bsqrt(x))+%2F+(1+-+sqrt(x)))+%2B+1.5)

I'm not sure what the code does though https://github.com/google/filament/blob/master/shaders/src/brdf.fs#L282

5a402dc6a8 Corrected exposure from ev100 formula (#518) 
The new formula should be the correct one according to this document (first line p86): https://seblagarde.files.wordpress.com/2015/07/course_notes_moving_frostbite_to_pbr_v32.pdf

55dd612c64 Add screenshots to Android samples' README (#513) 
This change also optimizes the size of existing images using squoosh.app.
This should make the main README a lot lighter and faster to load (it saves
several MiBs).

f78a680b9c Documentation grammar and typo fixes (#174) 
* Missing parameter in visibility function equation

The visibility function V_1 depends on l (or v) and alpha, but alpha was omitted in one equation.

* Fix typo its vs it is

* Fix typo usign -> using

* Fix typo algorightm -> algorithm

* Fix typo later -> latter

* Grammar: much less -> many fewer

* Fix missing equation label

Equation was referred to in the text, but did not have its label defined, causing the reference to show up as ???.

* Fix typo itentiy -> itentity

* Fix typo apperance -> appearance

* Fix typo participe -> participate

* Fix typo: scaterring -> scattering

* Consistency: grey -> gray

Since the document mostly uses American English, replace occurrences of "grey" (preferred spelling in UK) with "gray" (preferred spelling in US).
