*	Add the conversion in-place for QPixmap::fromImageReader() on raster.	Benjamin Poulain	2010-06-30	1	-0/+0
\| \| \| \| \| \| \| \|	Since raster uses QImage internal, QPixmap::fromImageReader() can use conversion in-place of the image. This avoid a memory peak during the conversion and is a bit faster. Reviewed-by: Samuel Rødal
*	Start the implementation of in-place recoding for images	Benjamin Poulain	2010-06-20	7	-0/+0
	Currently, with the graphics system raster, converting from images to QPixmap often needs to allocate a new image to convert the right format. For example, for an image in ARGB32 of 10 mbytes, we need to allocate a second image of 10 mbytes in ARGB32_PM to convert the source image in the right format for pixmap. This can create a hight peak of memory, and is a bit slower than it should. This patch introduce in-place conversion of images when they are loaded with QPixmap::loadFromData(). The images are loaded in their default format by QImageReader, and are then converted in-place, trying to reduce memory allocations. Reviewed-by: Samuel Rødal
