+// ==================== TEMPLATE IMPL. OF CHANNEL BLEND ========================
+/**
+* Template implementation of ChannelBlend. It is assumed that arithmetic
+* shifting is supported -> negative values are shifted correctly. Pitch is the
+* number of data elements to skip before moving to next line. Note that all
+* non-masked cases are also done with the alpha blended version (masks are
+* constants in that case).
+*
+* The next parameters are passed to blend functions:
+* aW      Bitmap width in pixels
+* aH      Bitmap height in pixels
+* aT      Target bitmap data address
+* aPT     Target bitmap scanline pitch
+* aA      Source bitmap A data address
+* aPA     Source bitmap A scanline pitch
+* aMA     Source bitmap A mask data address
+* aPMA    Source bitmap A mask scanline pitch
+* aB      Source bitmap B data address
+* aPB     Source bitmap B scanline pitch
+* aMB     Source bitmap B mask data address
+* aPMA    Source bitmap B mask scanline pitch
+* aFactor The blend factor between A and B on the output.
+*
+* Inside methods local variables have the following roles:
+* x   The current pixel's x position
+* y   The current pixel's y position
+* r   The resulting red color component
+* g   The resulting green color component
+* b   The resulting blue color component
+* sa  Currently processed source A color component
+* sb  Currently processed source B color component
+* ma  Mask A value for current pixel position
+* mb  Mask B value for current pixel position
+* ca  A RGB color value for current pixel position
+* cb  B RGB color value for current pixel position
