f6f6ebdb44 [FEATURE] API to enable/disable editing of raster data 
To create a 2x2 raster block with one byte per pixel:

```
block = QgsRasterBlock(Qgis.Byte, 2, 2)
block.setData(b'\xaa\xbb\xcc\xdd')
```

To overwrite existing raster data at position 0,0 by the 2x2 block:

```
provider.setEditable(True)
provider.writeBlock(block, band, 0, 0)
provider.setEditable(False)
```

532eb58d1f [FEATURE] Implement raster auto-stretching when updating canvas 
This commit implements the improvements described at:
https://lists.osgeo.org/pipermail/qgis-developer/2016-September/044393.html

The QgsRasterMinMaxWidget now offers a seetting to specify that the statistics
should be computed each time the canvas extent changes.

Other changes:
- the content of the QgsRasterMinMaxWidget is now persistant.
- there is no longer any Load button. The global Apply / OK button of the raster
  properties dialog has this effect.
- the default "limits" for single band raster is now MinMax and not CumulativeCut
- the default "limits" can be configured for single band, multi band single byte and
  multi band multi byte
- "Strech using current extent" honours the "limits" instead of forcing min/max.

fdeac8198c Fix incorrect raster reprojection after drawing raster previews 
Moved all temporary projector members to a private class,
so even recursive block() calls will not affect each other
(there is no new performance penalty as block() call always
recomputes the temporary control point matrix anyway)

b6b5afd885 [FEATURE] Ability to cancel rendering of rasters + WMS/WCS support 
The improvement allows immediate cancellation of raster rendering
in progress. Until now, even when map rendering got cancelled
(e.g. by zooming of panning canvas), the GUI got blocked while waiting
for raster layers to finish their rendering (only vector layers have
had support for cancellation). This should allow for much smoother
user experience while browsing maps including rasters.

The cancellation is supported currently by WMS/WMTS and WCS providers.
GDAL provider may also get support thanks to improvements in GDAL 2.
