For some reason I thought it's size of one face pre-ARB_DSA and size of
all six faces on ARB_DSA. NVidia drivers (which return different size
based on whether the texture is immutable, which is totally crazy)
didn't help with that at all. Now I realized this while fixing test
failures on Mesa. IIRC I couldn't find a clear explanation in the spec
anyway, so I'll just bite the bullet and assume *this* is the correct
way now. Mesa tests now pass instead of saying that my provided buffer
size is too small.
Also added a bunch of comments to prevent confusing myself again next
time and spaced the indices evenly to make them readable. All those
poorly done things contributed to the bug.
Followup to previous commit -- links to opengl.org are now redirected to
khronos.org and the extension links have the same format for both GL and
GLES. That allows me to remove some of the Doxygen aliases and use just
a single set of the functions for both GL and GLES.
The move away from `nullptr` to NoCreate for constructing an application
without creating OpenGL context was done quite some time ago for
windowless application, but for some weird reason it was never done for
windowed apps. Now made this consistent.
The old `nullptr`-based constructor is still present, but marked as
deprecated and due to be removed in some future release.
Color-coded XY and XYZ axes, cut out of DebugTools::ObjectRender into a
better reusable piece of code. Using the new vertex color functionality
of mesh data.
It was just RGB before. In order to avoid breaking current code, the
attribute now requires explicit specification of number of components.
If building with deprecated APIs enabled, there is an additional
deprecated constructor that defaults to RGB so the current code should
keep working as-is.
In order to have a seamless transition for all the plugins and potential
user code the original constructor was marked as deprecated and there is
a new constructor taking also the colors.
