Previously, Cappuccino was using preprocessor macros internally for the CGPoint/Size/Rect/Inset/Affine functions, as well as for CPRange. These macros had the same name as the corresponding function, but began with _. The functions were actually defined using the macros.
The motivation behind using macros was to increase performance by reducing function calls. However, there were a number of problems with this approach:
- There was an artificial dichotomy between _CG macros and the corresponding CG functions. We never completely replaced CG function calls with _CG macros. In fact, they were often mixed up in the same file. There was an extra burden on the programmer to remember to use the macro instead of the function.
- If a method call was passed as an argument to a macro, performance could actually be significantly *worse* than a function call. For example, _CGGetRectMakeCopy([view frame]) would expand to `{ origin:{ x:[view frame].origin.x, y:[view frame].origin.y }, size:{ width:[view frame].size.width, height:[view frame].size.height } }`. So instead of a single objj_msgSend and a single simple function call, we ended up with 4 objj_msgSend calls, which are way more expensive than simple function calls.
- Because of this expansion problem, to use macros efficiently required us to remember to use variables for all macro parameters. This didn't happen, and shouldn't have to happen.
- Finally, with modern Javascript engines, function call overhead is so small that it really isn't worth using the macros.
This commit eliminates the _CGGeometry, CGAffineTransformation and CPRange macros and replaces them with function calls.
BREAKING CHANGE:
The macros are no longer available. They could only be used with compiled code, but if there is any user code that used them, they will have to be replaced with the corresponding functions.
Added documentation for tableView:dataViewForTableColum:row: delegate method. Document other cases, when we expect the data view to have a CPViewNotSizable mask.
ViewBasedCib example: added variable row heights.
- NEW: Retrieve the underlying Image element from a CPImage with -image.
- NEW: You can now render any arbitrary drawing to a pattern context and use that as a fill or stroke pattern. See CGContextCreatePatternContext, CGContextSetFillPattern and CGContextSetStrokePattern. Works in all canvas-enabled browsers, including IE 9+.
- NEW: An example of using a custom rendered pattern is in Tests/Manual/PatternFillTest.
- NEW: Test if a CPImage is a single image (vs. three/nine part) with -isSingleImage.
- FIXED: With canvas, we have to track ourselves whether the context has a path or not.
- FIXED: All shapes except rects may not be added to a path with no context. If you attempt to do so, an error is logged.
- FIXED: CGPath was not setting the start and current point correctly in some cases.
- FIXED: CGContextAddPath was not moving to the path's start point at the beginning.
- FIXED: Removed superfluous CGContextClosePath commands, fixed some drawing sequences.
- FIXED: Misc. formatting.
Sorry, these changes are canvas only (including IE 9+)! I am not going to spend the time to port these fixes to VML (IE 8).
- Removed stray console.error
- Made border of tooltips darker, they were almost invisible, even over a white background
- Added CGAlignStroke and CGAlignCoordinate, they are of general use
`CPTableView`'s `selectionIndexes` binding shouldn't be set automatically unless the content binding was also set automatically (through a table column binding).
Assume that manual content binding implies a desire to manually bind selection indexes (and sort descriptors) as well.
