Overlay: Rearrange the font image
Each glyph is now placed in a separate layer, and the image is made
mipped. This is to prepare for FS-based rendering of the overlay and
provide more flexible sizing of the font.

Generators: Use fixed year in license headers.
Remove dynamic year generation from generator scripts, as required by
the Chromium C++ style guide.
The dynamic year values were replaced by the current year at the time
the file was created according to git log. The code to dynamically
generate the year was removed.
This patch also refreshes generated files and hashes.

Remove overlay font hash from codegen.
This prevents a presubmit error on Windows. Seems like the binary file
differs somehow. Remove it from the hashes until we can investigate.

Reland "Vulkan: Debug overlay"
This is a reland of e54d0f90d1a165404236fd7abd1b05ddd041a686
This was reverted due to a build failure as a result of a missing
virtual destructor in the widget base class.

Vulkan: Debug overlay
A debug overlay system for the Vulkan backend designed with efficiency
and runtime configurability in mind. Overlay widgets are of two
fundamental types:
- Text widgets: A single line of text with small, medium or large font.
- Graph widgets: A bar graph of data.
Built on these, various overlay widget types are defined that gather
statistics. Five such types are defined with one widget per type as
example:
- Count: A widget that counts something. VulkanValidationMessageCount
is an overlay widget of this type that shows the number of validation
messages received from the validation layers.
- Text: A generic text. VulkanLastValidationMessage is an overlay
widget of this type that shows the last validation message.
- PerSecond: A value that gets reset every second automatically. FPS is
an overlay widget of this type that simply gets incremented on every
swap().
- RunningGraph: A graph of last N values. VulkanCommandGraphSize is an
overlay of this type. On every vkQueueSubmit, the number of nodes in
the command graph is accumulated. On every present(), the value is
taken as the number of nodes for the whole duration of the frame.
- RunningHistogram: A histogram of last N values. Input values are in
the [0, 1] range and they are ranked to N buckets for histogram
calculation. VulkanSecondaryCommandBufferPoolWaste is an overlay
widget of this type. On vkQueueSubmit, the memory waste from command
buffer pool allocations is recorded in the histogram.
Overlay font is placed in libANGLE/overlay/ which gen_overlay_fonts.py
processes to create an array of bits, which is processed at runtime to
create the actual font image (an image with 3 layers).
The overlay widget layout is defined in overlay_widgets.json which
gen_overlay_widgets.py processes to generate an array of widgetss, each
of its respective type, and sets their properties, such as color and
bounding box. The json file allows widgets to align against other
widgets as well as against the framebuffer edges.
Two compute shaders are implemented to efficiently render the UI:
- OverlayCull: This shader creates a bitset of Text and Graph widgets
whose bounding boxes intersect a corresponding subgroup processed by
OverlayDraw. This is done only when the enabled overlay widgets are
changed (a feature that is not yet implemented) or the surface is
resized.
- OverlayDraw: Using the bitsets generated by OverlayCull, values that
are uniform for each workgroup (set to be equal to hardware subgroup
size), this shader loops over enabled widgets that can possibly
intersect the pixel being processed and renders and blends in texts
and graphs. This is done once per frame on present().
Currently, to enable overlay widgets an environment variable is used.
For example:
$ export ANGLE_OVERLAY=FPS:VulkanSecondaryCommandBufferPoolWaste
$ ./hello_triangle --use-angle=vulkan
Possible future work:
- On Android, add settings in developer options and enable widgets based
on those.
- Spawn a small server in ANGLE and write an application that sends
enable/disable commands remotely.
- Implement overlay for other backends.
