I've got a custom QQuickImageProvider that I want to have always rendered at 
native resolution.
However on every call requestedSize is QSize(-1, -1) forcing me to use my 
default resolution which then gets scaled, which gives me fuzzy pixels. 

I thought maybe fillMode was an issue, but is it not. Even with an explicit 
height and width in the Image, it never changes from QSize(-1, -1).

Then, I was reading the docs and it says 
'''
Image Caching
Images returned by a QQuickImageProvider are automatically cached, similar to 
any image loaded by the QML engine. When an image with a "image://" prefix is 
loaded from cache, requestImage() and requestPixmap() will not be called for 
the relevant image provider. If an image should always be fetched from the 
image provider, and should not be cached at all, set the cache property to 
false for the relevant Image, BorderImage or AnimatedImage object.
'''

However setting cache: false in the Image element does not change anything.

I've also set 
painter.setRenderHint(QPainter::Antialiasing, false);
painter.setRenderHint(QPainter::SmoothPixmapTransform, false);
In painter and I still get blurry output. I want aliased pixels like in the 
Concentric Circles example.

I've tried various achorings, fillModes, widths and heights.

Does anyone have any pointers? I would expect that the requested size be the 
pixel dimensions of the Image requesting it?
