Changes of d245dc9e1f (Fix drawing of dotted lines with wxDC in wxMSW,
2020-03-27) improved the appearance of dotted and dashed lines in wxMSW
but at the expense of significant (up to a factor of 300) slowdown.
Allow the applications for which the drawing performance is important to
explicitly request the old behaviour, with uglier, but faster, pens by
choosing to use low quality pens.
Update the graphics benchmark to allow specifying the pen quality and
verify that the performance when using it is the same as before 3.1.4.
See https://github.com/wxWidgets/wxWidgets/pull/2218
See #7097.
Closes#18875.
Handle the case of a single line string specially, it's faster to do
this than use slow loop over all characters.
Also avoid constructing the string with the characters to measure one by
one and do it all at once instead.
Add a possibility to benchmark GetMultiLineTextExtent() rather than
GetTextExtent() in the graphics benchmark.
Since the performance of drawing lines with various pen styles can be the subject of examination it would be good to have the ability to select pen style with a command line option.
So, a new option "pen-style" is supported since now and with this new option "solid", "dot", "long_dash", "short_dash" styles can be explicitly selected.
Since for some renderers circles and/or ellipses are basic figures so it would be worth to test the performance of drawing them.
Respective tests are enabled with new command line options: "--circles" or "--ellipses".
Since there are several graphics renderers available under wxMSW it would be good to have ability to test graphics performance of any of them and not only the performance of default one.
Therefore new feature to run the tests with selected graphics renderer has been implemented in the benchmark application. Renderer can be selected with optional command line option: "/r renderer_name", when `renderer_name` can be either gdiplus, direct2d, cairo.
When no renderer is explicitly selected then default renderer is used.
Extended tests to determine speed of drawing RGB/ARGB bitmaps on target
bitmaps with different colour depths (RGB/0RGB/ARGB/system default).
See #16766.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

Draw the bitmap using OpenGL textures. Even without using PBO this results in
much greater performance than using wxImage or raw bitmap access.

It's not used for lines only, so call it "number of iterations" and not
"number of lines" and use "N" instead of "L" option for it.

Compare the speed of drawing the bitmaps by synthesizing wxImage and
converting it to wxBitmap and directly modifying wxBitmap bits using raw
bitmap access.

Still run all the tests by default but allow specifying --dc or --gc as well
as --paint, --client or --memory to test just the specified kinds of DCs.

These tests were not run because OnPaint() handler was called before OnCreate()
and exited the main loop before the create event could be dispatched. Fix this
by just running everything from OnPaint(), like this we're sure to do it.
Also refactor the code a little to avoid duplicating the tests.

- use correct printf format specifiers
- don't perform operations requiring a window until the window has been created

Use "wxWindows licence" and not "wxWidgets licence" (the latter doesn't
exist) and consistently spell "licence" using British spelling.
