In short, for mixed environments such as the Steam Runtime and other
container-like environments, choosing which libdrm to link into the
client's address space is a hard problem. If the runtime has a newer
libdrm than the host, then it should be preferred, because the client
may be using newly-added symbols. But if the host has a newer libdrm,
then that should be used, because drivers may be depending on those.
Bumping the DSO minor version is transparent to all users because apps
only link against the major version, e.g. DT_NEEDED libdrm.so.2; the
fact that libdrm.so.2 is a link to libdrm.so.2.122.0 is a detail known
only to the loader, but it does let a smart runtime make better
decisions.

The final goal is to enable asynchronous operation of the

The function currently checks for each added command
if an overflow of the corresponding command buffers
occurs, but none of the callers ever checks the
return value.
Since all callers are now converted to use
g2d_check_space() simplify the function.
(1) The overflow checks become asserts, so they're only
active for debug builds. This is fine since
g2d_add_cmd() is not part of the public API.
(2) Switch the return value to void.
(3) Explicitly state that the caller has to check
buffer space before calling g2d_add_cmd().

The G2D headers define a number of modes through enums
(like e.g. color, select, repeat, etc.).
This introduces g2d_validate_select_mode() and
g2d_validate_blending_op() which validate a
select mode or blending operation respectively.
Use this together with g2d_check_space() in
g2d_{blend,scale_and_blend}().
For this we move parameter validation to the top and
also validate the select mode of the source image and
the requested blending operation before starting
command submission.

This is going to be used to check if the command buffers have

Use this in g2d_{solid_fill,copy,copy_with_scale}().
For this the parameter validation before buffer space

Also don't reset the G2D context in this situation since
the buffers are not partially submitted anymore.
The repeat mode in g2d_copy_with_scale() is checked first
to make computation of space easier.
