If one of the descriptor sets doesn't have any items, don't include it
in the sets passed to vkUpdateDescriptorSets().
This has no effect right now, because we either have both images and
samplers or neither, but it will become relevant once we also support
buffers.
Sometimes the GPU is still busy when the next frame starts (like when
no-vsync benchmarking), so we need to keep all those resources alone and
create new ones.
That's what the render object is for, so we just create another one.
However, when we create too many, we'll starve the CPU. So we'll limit
it. Currently, that limit is at 4, but I've never reached it (I've also
not starved the GPU yet), so that number may want to be set lower/higher
in the future.
Note that this is different from the number of outstanding buffers, as
those are not busy on the GPU but on the compositor, and as such a
buffer may have not finished rendering but have been returend from the
compositor (very busy GPU) or have finished rendering but not been
returned from the compositor (very idle GPU).
The idea here is that we can do more complex combinations and use that
to support texture-scale nodes or use fancy texture formats (suc as
YUV).
I'm not sure this is actually necessary, but for now it gives more
flexibility.
Instead of having a descriptor set per operation, we just have one
descriptor set and bind all our images into it.
Then the shaders get to use an index into the large texture array
instead.
Getting this to work - because it's a Vulkan extension that needs to be
manually enabled, even though it's officially part of Vulkan 1.2 - is
insane.
1. Use a graphene_vec2_t
2. Ensure it's always positive
3. Don't break with fallback
The scale value is nothing more than an indication of how many pixels to
assume per unit of a node.
gsk_vulkan_render_download_target() currently resets the uploader
objects before downloading the image that it produces. This is
problematic because there might be unreleased buffers and images
in the command queue.
In particular, this can make validation layers complain about the
glyph atlas - of all things! - upload buffer being released while
still being used by the command queue.
Fix that by resetting the uploader after downloading the image.
Basically what GL does, but without any debug or feature flag
to gatekeep it, since the Vulkan backend itself is experimental
already.
Ceil surface sizes, and floor coordinates, to the fractional scale
value.
Instead of tracking a single scale, track x and y scales separately.
Factor out gsk_vulkan_render_pass_new() into a private function that
receives both scales, and pass 'scale_factor' for both.
Now that we have the full render nodes available, there is not much
benefit in fine-grained control over multiple rectangles.
In particular, it's causing pain with complex regions.
There might be a benefit in clipping to the region's rectangles in cases
like widget-factory where the whole diff is made up of the 2 rectangles
of spinner and the pulsing progress bar, but it needs a good heuristic
for where this is useful.
