f08d239578 Use QPolygonF for connect='all'
Since QDataStream >> QPainterPath is an expensive operation, we can
construct our QPainterPath from an open polygon instead but only if the
connect='all' mode is present.  Future optimizations work can likely
be had with constructing a polygon from each connected segment

Bypass makeARGB in some cases (#1786)
* refactor out _ndarray_to_qimage()

* combine levels back with lut

* make use of Grayscale8, RGB888 and Indexed8 QImage formats

Grayscale8 and RGB888 images are those that are ready for display
without further processing.

* add Grayscale16

* apply the efflut early for uint16 mono/rgb, uint8 rgb

* ndarray indexing is faster than np.take

* handle uint16 rgb(a) with no levels same as levels=[0, 65535]

* add support for Format_RGBA64

* fix: support colormaps of shape (h, 1)

* check ImageItem uint8 and uint16 QImage formats

* uint16 mono with rgb lut -> RGBX8888

* got width and height swapped in array dimensions

* set ImageItem as row-major

* no need to form a 1d 32-bit lut for array indexing

you can index (y, x) into a lookup table of shape (nentry, 3) or
(nentry, 4) and get an output of shape (y, x, 3) or (y, x, 4)

* Revert "no need to form a 1d 32-bit lut for array indexing"

This reverts commit 45cf3100de.

* distinguish between levels_lut and colors_lut

this allows uint16 images with user lut to be rendered as
Format_Indexed8

* uint8 (1-chan) images should always combine to efflut

this efflut will then be used for Indexed8 format color table.

previously, we would be taking a performance hit with doing a numpy
lookup with levels_lut.

* adapt benchmarks/makeARGB.py to renderImageItem.py

* restructure uint8 and uint16 codepaths

* normalize 1-chan images to ndim==2 earlier up

* refactor long code into functions

* bug: qimage may not be assigned

* fix: assign to self.qimage only if not None

* for uint16, do rescale rather than do levels_lut lookup

* cases 2,3 are already handled

i.e. no more using lut to do rescale of uint16 image data.

* rescale rgb images by computation, not by memory lookup

* setImage() does not take an output argument

* try to be cupy compatible

use "xp" instead of numpy module

* add numba to benchmarking

* fix: lut_big is dtype uint8 with more than 256 entries

* bug: applying colors_lut needs C-order

* support float with no nans

* fix: variable could be uninitialized

* add float32 format tests

* avoid explicitly forcing to C-contiguous

* cache effective lut only if combination took place

every one of the four branches now does its own return.
this makes it easier to follow.

* fix cupy benchmark : typo in renderQImage

* remove for loop of 1 iteration

* use float32 for floating point benchmark

* superceded by renderImageItem.py

* lint

* benchmark without lut conversion

* put the lut onto the substrate

* fix editor complaints

* handle lack of cupy

* leading underscores imply privacy
