add debug:gl_debugging so we can disable gl debugging entirerly,
both glGetError and enabling EGL_KHR_debug has its cost, we still have
EXT_create_context_robustness and glGetGraphicsResetStatus that should
catch context loss, and is generally cheap to call it only checks a flag
set.
glGetError might cause a implicit flush to get any pending calls sent to
the gpu.
however to get EGL_KHR_debug back enabled we now require a restart of
the compositor after changing debug:gl_debugging
These are: pointer_shape from the cursor-shape-v1 protocol prepared for v2, along with left_ptr...bottom_right_corner and killing (Hyprland specific)
pointer_shape_previous with
pointer_switch_time to blend between shapes
pointer_size scaled size as used by the normal cursor
pointer_pressed_positions[32] with
pointer_pressed_times[32] and
pointer_pressed_killed(32 bits) for click/touch animations and if they killed something
pointer_inactive_timeout with
pointer_last_active to smoothly fade the pointer out
pointer_hidden to hide it when the cursor is hidden (excluding by cursor:invisible as this config value can be used to turn off the normal cursor, which is useful when drawing it with the screen shader)
* opengl: cache viewport state
according to nvidia docs calling glViewPort unnecessarily on the same
already set viewport is wasteful and can cause state changes when not
needed. cache it in a struct and only call it when the viewport is
actually changing.
* opengl: cache glenable/gldisable state
avoid making multiple glenable/gldisable calls on already set caps, can
cause state changes and incur driver overhead.
* opengl: cache glscissor box
only call glscissor if the box actually has changed, try to avoid state
changes.
* opengl: cache gluniform calls
cache the gluniform calls, the uniform values are cached in driver per
program only the drawcalls setting the uniform yet again with the same
value on same location is causing more overhead then caching it ourself
and just no oping on it if no changes.
* shader: rewrite handling of uniforms and state
this is way faster as we don't need to mess with maps (hashing, etc) and instead can just use an array
* opengl: stuff and 300 shaders
* opengl: typo
* opengl: get the uniform locations properly
now that the legacy shaders are gone get the uniformlocations for
SKIP_CM etc, so they can be properly set and used depending on if
cm_enabled is set to false or true, before it was falling back to a
legacy shader that didnt even have those uniforms.
* opengl: check epsilon on float and remove extra glcall
seems an extra unset glcall was added, remove it. and check the float
epsilon on the glfloat.
* opengl: remove instanced shader draw
remove the instanced boolean from the vertex shader, might be neglible
differences, needs more benchmark/work to see if its even worth it.
* texture: cache texture paramaters
parameters where occasionally set twice or more on same texture, short
version wrap it and cache it. and move gpu churn to cpu churn.
add a bind/unbind to texture aswell.
* texture: use fast std::array caching
cache the texparameter values in fast array lookups
and incase we dont want it cached, apply it anyways.
* shader: fix typo and hdr typo
actually use Matrix4x2fv in the 4x2fv cache function, and send the
proper float array for hdr.
* texture: make caching not linear lookup
make caching of texture params not linear.
* minor style changes
* opengl: revert drawarrays
revert the mostly code style reduce loc change of drawarrays, and focus
on the caching. its a if else case going wrong here breaking
blur/contrast amongst others drawing.

* make functions used in 1 file static
* fix invalid substr param -1
* give default initializer to borderGradier
* move RASSERT from printf to std::print
* framebuffer: avoid gluint overflow
GLuint was being initialized to -1 and rolling over to unsigned int max,
its defined behaviour but very unnecessery. add a bool and use it for
checking if allocated or not.
* opengl: avoid gluint rollover
-1 rolls over to unsigned int max, use 0xFF instead.
* core: big uint64_t to int type conversion
there were a few uint64_t to int implicit conversions overflowing int
and causing UB, make all monitor/workspaces/windows use the new
typedefs. also fix the various related 64 to 32 implicit conversions
going around found with -Wshorten-64-to-32
* core: move to hyprutils for utils
Nix: add hyprutils dep
* Meson: add hyprutils dep
* flake.lock: update

moves std::shared_ptrs to a new implementation
Advantages:
- you can dereference a weak_ptr directly. This will obviously segfault on a nullptr deref if it's expired.
- this is useful to avoid the .lock() hell where we are 100% sure the pointer _should_ be valid. (and if it isn't, it should throw.)
- weak_ptrs are still valid while the SP is being destroyed.
- reasoning: while an object (e.g. CWindow) is being destroyed, its `weak_ptr self` should be accessible (the sp is still alive, and so is CWindow), but it's not because by stl it's already expired (to prevent resurrection)
- this impl solves it differently. w_p is expired, but can still be dereferenced and used. Creating `s_p`s is not possible anymore, though.
- this is useful in destructors and callbacks.
