'size' and 'rect' are names that should be avoided. In Qt 6 newer code, such as QRhi, explicitly uses pixelSize instead of size, and this is visible in some of the newer Qt Quick code as well, but old code from Qt 5 times suffers from confusion still: even though on the scenegraph level "everything" is in pixels, there are things that aren't, for example the "rect" that gets passed to the projection matrix calculation is in logical units! Comprehension and maintenance gets challenged also when there are higher level "size", "rect", "textureSize", etc. kind of names in QQuickItem and elsewhere that are not necessarily in pixels yet can be mistaken to map 1:1 to the scenegraph data. Try to indicate this in argument and member names. Also add a missing word to the QSGTexture docs. The overview mentions this in fact but the function doc does not.
