Mass api change from GtkExtendedLayout --> GtkSizeRequest This commit makes a few massive changes to the extended layout code: a.) gtkextendedlayout.c --> gtksizerequest.c b.) _is_height_for_width --> get_request_mode() c.) get_desired_size(), get_desired_width(), get_desired_height() --> get_size(), get_width(), get_height() This is the first partial commit and only effects portions of the tree that have already been merged in master (in order to easily cherry pick this commit).

This patch optimizes window resizes by assuming that if a widget has the same height at a width of 50 as with a width of 150, the height for width 100 will also be the same. The patch also further optimizes the cache allocator, now there are 2 pointer arrays of up to a maximum of 5 requests, the arrays will only be allocated if a request is ever made in that orientation and the array will be sparse until each request is made (i.e. if a label can only wrap to 3 lines, there will only be 3 out of a possible 5 SizeRequest structures allocated to cache it).

Initial support for baselines This modifies the size machinery in order to allow baseline support. We add a new widget vfunc get_preferred_height_and_baseline_for_width which queries the normal height_for_width (or non-for-width if width is -1) and additionally returns optional (-1 means "no baseline") baselines for the minimal and natural heights. We also add a new gtk_widget_size_allocate_with_baseline() which baseline-aware containers can use to allocate children with a specific baseline, either one inherited from the parent, or one introduced due to requested baseline alignment in the container itself. size_allocate_with_baseline() works just like a normal size allocation, except the baseline gets recorded so that the child can access it via gtk_widget_get_allocated_baseline() when it aligns itself. There are also adjust_baseline_request/allocation similar to the allocation adjustment, and we extend the size request cache to also store the baselines.

sizerequest: Optimize CONSTANT_SIZE better We can set for_size to -1 earlier than we did. Doing so makes sure we only cache one value (as we should in the first place). In GTK 3.6, this worked properly, but with Previously, this check was moved further up to avoid interacting with size groups. But after recent refactorings, size groups are handled way earlier anyway.

We also add a new gtk_widget_size_allocate_with_baseline() which baseline-aware containers can use to allocate children with a specific baseline, either one inherited from the parent, or one introduced due to requested baseline alignment in the container itself. size_allocate_with_baseline() works just like a normal size allocation, except the baseline gets recorded so that the child can access it via gtk_widget_get_allocated_baseline() when it aligns itself. There are also adjust_baseline_request/allocation similar to the allocation adjustment, and we extend the size request cache to also store the baselines.

* gtk_widget_get_request_mode:
Move GtkSizeRequest into GtkWidget It doesn't make sense to keep them separate as GtkSizeRequest requires a GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have one without the other.

Also, the names would translate to gtk_widget_get_width() and people agreed that this would be a too generic name, so a "preferred" was added to the names.

Mega commit to change ->get_desired_size() for ->get_desired_width/height(). This commit changes gtk_extended_layout_get_desired_size() for per dimension variants. Furthermore this commit reverts the actions done in size-groups for now as it needs a different approach. The natural width/height parameters added to aux_info have been changed for a per width cache for heights and a per height cache for widths. gtk-demo is still working, currently sizegroups are not taken into account as mentioned above - size groups need to be alerted both when the widths and heights are updated independantly and then that information needs to repropagate also to other extended layout implementors.

Move GtkSizeRequest into GtkWidget It doesn't make sense to keep them separate as GtkSizeRequest requires a GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have one without the other. It also makes the code a lot easier because no casts are required when calling functions. Also, the names would translate to gtk_widget_get_width() and people agreed that this would be a too generic name, so a "preferred" was added to the names. So this patch moves the functions: gtk_size_request_get_request_mode() => gtk_widget_get_request_mode() gtk_size_request_get_width() => gtk_widget_get_preferred_width() gtk_size_request_get_height() => gtk_widget_get_preferred_height() gtk_size_request_get_size() => gtk_widget_get_preferred_size() gtk_size_request_get_width_for_height() => gtk_widget_get_preferred_width_for_height() gtk_size_request_get_height_for_width() => gtk_widget_get_preferred_height_for_width() ... and moves the corresponding vfuncs to the GtkWidgetClass. The patch also renames the implementations of the vfuncs in widgets to include the word "preferrred".

Added gtk_extended_layout_is_height_for_width() Added an indicator telling whether a widget prefers to be allocated as height-for-width or width-for-height. Usually this depends on the orientation of a container or the nature of a content widget like GtkLabel. This indicator is only used in the seldom case where a parent is allocating free space to the child and the child can flow in either direction, GtkWindow and GtkScrolledWindow are users of this api.

We also add a new gtk_widget_size_allocate_with_baseline() which baseline-aware containers can use to allocate children with a specific baseline, either one inherited from the parent, or one introduced due to requested baseline alignment in the container itself. size_allocate_with_baseline() works just like a normal size allocation, except the baseline gets recorded so that the child can access it via gtk_widget_get_allocated_baseline() when it aligns itself. There are also adjust_baseline_request/allocation similar to the allocation adjustment, and we extend the size request cache to also store the baselines.

Move GtkSizeRequest into GtkWidget It doesn't make sense to keep them separate as GtkSizeRequest requires a GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have one without the other. It also makes the code a lot easier because no casts are required when calling functions. Also, the names would translate to gtk_widget_get_width() and people agreed that this would be a too generic name, so a "preferred" was added to the names. So this patch moves the functions: gtk_size_request_get_request_mode() => gtk_widget_get_request_mode() gtk_size_request_get_width() => gtk_widget_get_preferred_width() gtk_size_request_get_height() => gtk_widget_get_preferred_height() gtk_size_request_get_size() => gtk_widget_get_preferred_size() gtk_size_request_get_width_for_height() => gtk_widget_get_preferred_width_for_height() gtk_size_request_get_height_for_width() => gtk_widget_get_preferred_height_for_width() ... and moves the corresponding vfuncs to the GtkWidgetClass.

Initial support for baselines This modifies the size machinery in order to allow baseline support. We add a new widget vfunc get_preferred_height_and_baseline_for_width which queries the normal height_for_width (or non-for-width if width is -1) and additionally returns optional (-1 means "no baseline") baselines for the minimal and natural heights. We also add a new gtk_widget_size_allocate_with_baseline() which baseline-aware containers can use to allocate children with a specific baseline, either one inherited from the parent, or one introduced due to requested baseline alignment in the container itself. size_allocate_with_baseline() works just like a normal size allocation, except the baseline gets recorded so that the child can access it via gtk_widget_get_allocated_baseline() when it aligns itself. There are also adjust_baseline_request/allocation similar to the allocation adjustment, and we extend the size request cache to also store the baselines.

* a) Maximize number of children taking their natural size.
* b) The allocated size of children should be a continuous
* function of c_gap. That is, increasing the container size by
* one pixel should never make drastic changes in the distribution.
* c) If child i takes its natural size and child j doesn't,
* child j should have received at least as much gap as child i.
*
* The following code distributes the additional space by following
