Merge branch 'master' into sculpt-mode-features

Cleanup: redundant NULL initialization

Cleanup: use shader config for worldspace clipping lib

UI: support Ctrl-C copy for popover buttons

Match menu logic that sets the Python expression to call the popover.

GPU: State: Replace GL_LINE_SMOOTH by GPU_line_smooth

GPU: State: Disable polygon smooth and line smooth when running --debug-gpu

This might prove usefull when debugging some driver perf issues.

GPU: Replace glEnable/glDisable but GPU_state calls

GPU: Remove unused and deprecated GPU_line_stipple()

Fix T62884 Missing control point in unselected mask handles

The fix is a bit dirty. Force alpha 1.0 for these colors by using
immUniformThemeColorShadeAlpha with 255 as alpha_offset.

Fix T62869 Transparent background not working in Xray Mode / Wireframe

This was due to the forward part of the engine not supporting rendered
alpha channel.

Fix T62873 GPUShader: compile error (when clipping in viewport)

Props to @matc for the fix

Fix T62097 Bone transparancy not enabled when Xray enabled

This forces bone transparency / wireframe display when Xray is enabled.
This makes sense as the bone transparency is a kind of Xray and should
be linked to the Xray display.

Eevee: Opti: Don't consider lights that have no power

This may be usefull if power is animated ans is to be activated at one
particular point in time.

Cleanup: Remove printf

Fix T62845 VSE preview crash when setting rendered (EEVEE/Workbench)

Edit Mesh: Rework "in front" + "hidden wire" drawing

Instead of doing some fancy stencil buffer tricks, just clear the depth
buffer before the "in front" meshes.

Fix T58841 Hidden Wire when in Edit Mode disables In Front Option

Fix workbench object outline ignoring clipping

Workbench forward engine wasn't recompiling shaders when clipping
changed, use GPUShaderConfigData when creating shaders.

Cleanp: remove redundant clipping uniform

workbench_material_shgroup_uniform handles this.

UI: show camera sensor 'Width' as 'Size' for 'Auto' fit

Fix auto sensor size for camera gizmo
