* Instead of just configuring SPIR-V disassemblers and picking only the first
one when we need to edit SPIR-V, we allow setting up any shader processor that
goes between two shader encodings.
* When editing, the default will still be to use embedded source, and then after
that the first tool that goes from the native shader format to a text format,
but the drop-down allows you to pick any of them.
* Similarly in the shader viewer you can configure the compilation options and
method, to choose the compiler you want to use. Embedded command line
parameters in the shader are automatically appended.
* Dock panels shouldn't have any frame border or anything like that.
* They should have an external margin of 3 pixels at their border,
but then no further margins on the layouts (like sub-controls for
the pipeline state views.
* Toolbars should be Raised & Panel frames. Later we'll replace them
with actual QToolBars to better customise the painting.
* We need to custom paint the SVG at the right devicepixelratio because
Qt seems to be busted at scaling up - nothing I can see causes the
SVG to be rendered at higher than it's default resolution, so you end
up with plain bilinear upscale.
* Since we're doing custom palette swap anyway, it's not much harm to
just render ourselves, as we already basically had a dependency on
QtSvg - just need to add the include files to the dependencies.
* Add scroll areas for the larger tabs and allow pipe flowchart to
resize to its minimum size if needed.
* The idea here isn't that anyone will seriously try to use the pipe
view at 500x200 but more that the minimum size doesn't become a
problem while moving around windows or panels, or resizing temporarily
* This was only added because the default tree widget controls don't
render any grid lines. Now that we're custom drawing them, the row
colors are distracting and can be confusing on themes where the
selected row is very faint.
* Since we're promoting everything, we reset the behaviour of
RDTreeWidget so that it's not doing anything different by default.
* RDTreeWidget's interface is a bit different, exposing some useful
things like a single selected item and so on.
* We also can't set columns in the Qt Creator UI anymore, so we set them
from code.
* Things like addressing modes, stencil operations, and other things the
UI didn't need to know about previously were only exposed as string
values to be passed through and displayed.
* Now we describe these with enums so the API can be properly
introspected and used by consumers that might want to know the actual
values of these states.
