-/**
- * exaTryMagicTwoPassCompositeHelper implements PictOpOver using two passes of
- * simpler operations PictOpOutReverse and PictOpAdd. Mainly used for component
- * alpha and limited 1-tmu cards.
- *
- * From http://anholt.livejournal.com/32058.html:
- *
- * The trouble is that component-alpha rendering requires two different sources
- * for blending: one for the source value to the blender, which is the
- * per-channel multiplication of source and mask, and one for the source alpha
- * for multiplying with the destination channels, which is the multiplication
- * of the source channels by the mask alpha. So the equation for Over is:
- *
- * dst.A = src.A * mask.A + (1 - (src.A * mask.A)) * dst.A
- * dst.R = src.R * mask.R + (1 - (src.A * mask.R)) * dst.R
- * dst.G = src.G * mask.G + (1 - (src.A * mask.G)) * dst.G
- * dst.B = src.B * mask.B + (1 - (src.A * mask.B)) * dst.B
- *
- * But we can do some simpler operations, right? How about PictOpOutReverse,
- * which has a source factor of 0 and dest factor of (1 - source alpha). We
- * can get the source alpha value (srca.X = src.A * mask.X) out of the texture
- * blenders pretty easily. So we can do a component-alpha OutReverse, which
- * gets us:
- *
- * dst.A = 0 + (1 - (src.A * mask.A)) * dst.A
- * dst.R = 0 + (1 - (src.A * mask.R)) * dst.R
- * dst.G = 0 + (1 - (src.A * mask.G)) * dst.G
- * dst.B = 0 + (1 - (src.A * mask.B)) * dst.B
- *
- * OK. And if an op doesn't use the source alpha value for the destination
- * factor, then we can do the channel multiplication in the texture blenders
- * to get the source value, and ignore the source alpha that we wouldn't use.
- * We've supported this in the Radeon driver for a long time. An example would
- * be PictOpAdd, which does:
- *
- * dst.A = src.A * mask.A + dst.A
- * dst.R = src.R * mask.R + dst.R
- * dst.G = src.G * mask.G + dst.G
- * dst.B = src.B * mask.B + dst.B
- *
- * Hey, this looks good! If we do a PictOpOutReverse and then a PictOpAdd right
- * after it, we get:
- *
- * dst.A = src.A * mask.A + ((1 - (src.A * mask.A)) * dst.A)
- * dst.R = src.R * mask.R + ((1 - (src.A * mask.R)) * dst.R)
- * dst.G = src.G * mask.G + ((1 - (src.A * mask.G)) * dst.G)
- * dst.B = src.B * mask.B + ((1 - (src.A * mask.B)) * dst.B)

+/**

+ * exaTryMagicTwoPassCompositeHelper implements PictOpOver using two passes of

+ * simpler operations PictOpOutReverse and PictOpAdd. Mainly used for component

+ * alpha and limited 1-tmu cards.

+ *

+ * From http://anholt.livejournal.com/32058.html:

+ *

+ * The trouble is that component-alpha rendering requires two different sources

+ * for blending: one for the source value to the blender, which is the

+ * per-channel multiplication of source and mask, and one for the source alpha

+ * for multiplying with the destination channels, which is the multiplication

+ * of the source channels by the mask alpha. So the equation for Over is:

+ *

+ * dst.A = src.A * mask.A + (1 - (src.A * mask.A)) * dst.A

+ * dst.R = src.R * mask.R + (1 - (src.A * mask.R)) * dst.R

+ * dst.G = src.G * mask.G + (1 - (src.A * mask.G)) * dst.G

+ * dst.B = src.B * mask.B + (1 - (src.A * mask.B)) * dst.B

+ *

+ * But we can do some simpler operations, right? How about PictOpOutReverse,

+ * which has a source factor of 0 and dest factor of (1 - source alpha). We

+ * can get the source alpha value (srca.X = src.A * mask.X) out of the texture

+ * blenders pretty easily. So we can do a component-alpha OutReverse, which

+ * gets us:

+ *

+ * dst.A = 0 + (1 - (src.A * mask.A)) * dst.A

+ * dst.R = 0 + (1 - (src.A * mask.R)) * dst.R

+ * dst.G = 0 + (1 - (src.A * mask.G)) * dst.G

+ * dst.B = 0 + (1 - (src.A * mask.B)) * dst.B

+ *

+ * OK. And if an op doesn't use the source alpha value for the destination

+ * factor, then we can do the channel multiplication in the texture blenders

+ * to get the source value, and ignore the source alpha that we wouldn't use.

+ * We've supported this in the Radeon driver for a long time. An example would

+ * be PictOpAdd, which does:

+ *

+ * dst.A = src.A * mask.A + dst.A

+ * dst.R = src.R * mask.R + dst.R

+ * dst.G = src.G * mask.G + dst.G

+ * dst.B = src.B * mask.B + dst.B

+ *

+ * Hey, this looks good! If we do a PictOpOutReverse and then a PictOpAdd right

+ * after it, we get:

+ *

+ * dst.A = src.A * mask.A + ((1 - (src.A * mask.A)) * dst.A)

+ * dst.R = src.R * mask.R + ((1 - (src.A * mask.R)) * dst.R)

+ * dst.G = src.G * mask.G + ((1 - (src.A * mask.G)) * dst.G)

+ * dst.B = src.B * mask.B + ((1 - (src.A * mask.B)) * dst.B)
