Cleanup code

Cycles: Background lights works with light tree

Added support for background lights when using the
light tree, fixed minor bugs related to disabled lights
and trying to build the light tree without any lights.

Now samples either the light tree, distant lights or
background lights based on their energy.

Fix draw back error due z-depth precission

The value 1.0 makes the image disappear.

Workbench: remove runtime warnings

Added feature check when uploading material uniforms

Fix problem when increase viewport qualitty

The reason of the problem was the precission of the background buffer. The original value was not enough when viewport qualitty was > 0.1

Cleanup unused extern definition

This was part of old VFX modifiers.

Fix again the pointer name for textures

Workbench: TAA optimalization

First frame of the TAA is just a regular copy of the previous buffer. so
we write directly to the final buffer and skip the taa shader. We do
init the history buffer via blit so it will be initialized for the other
iterations.

Cleanup: trailing newlines

Keymap: 2.7x macos-only additions

Keymap: add 2.7x keymap

This is the keymap from 929c78e33c06f55af4a3d98240959c4afcf9f39c
before the 2.8x keymap diverged from 2.7x.

All non-modal maps have been included.

Write all non modal keymaps

Workbench: Use less GPU memory

When AA was enabled a new buffer was created. As the composite pass is
already done, we can reuse earlier buffers.

For the deferred rendering we reuse the color_buffer_tx and for the
forward rendering we reuse the transparect_accum_tx.

Workbench: Removed MaterialData UBO

Most of the times the materials differ due to the object_id. This was an
overhead and resulted in instabilities on Intel graphical cards. This
commit will revert the Material Data UBO and replace it with normal
uniform.

removed line styles from SceneLANPR
