      Crunch ROM icon sprites · e62f3580
      Jeffrey Lee authored
      Save around 50KB of ROM space by converting the icon sprites to use RISC
      OS 3.5 mode words instead of numbered modes, reducing the size of the
      mask data to around a quarter of its old value.
      
      Tested in IOMD ROM, with boot sequence disabled (to ensure the ROM
      sprites get used).

      Fixes for dropping text into writable icons · 30c0dbf5
      Andy Vawer authored
      * If dragging text from a writable icon and the source text or selection disappears during the drag, an ofla error occurs. Change to abort quietly (ie no text copied as nothing to copy) and remove the ghost caret from view.
      * Remove ghost caret on invalid dropped drags
      * Either use correct insert point from ghost caret when receiving a drag, or use current mouse coords for the destination if no ghost caret present.
      * Change datasave handling to check ghost caret presence for the destination rather than trying to check the enhanced datasave state.
      * Use window X coord for drop rather than screen Xcoord to ensure correct insert point.
      
      Fixes dragging multiline text areas from Draw leaving a ghost caret when it failed, and dragging a basic text object from Draw now inserts at the correct place.

      Add Wimp_Extend 15, "read slot size" · 4610877c
      Jeffrey Lee authored
      Wimp_Extend 15 is equivalent to Wimp_SlotSize,-1,-1, with the exception
      that the sizes returned in R0-R2 are now measured in pages instead of
      bytes. This allows code to accurately read the amount of free memory on
      machines with >2GB of RAM, and provides some future-proofing should we
      ever wish to support tasks with >2GB of RAM (e.g. via a future
      super-jumbo wimpslot, or more likely via sparse/PMP wimpslots, where
      the physical size is larger than the logical size).
      
      Currently there's no need to provide a page-based call to set the slot
      size (~2GB is fine for the forseeable future), so this call only
      focuses on reading the sizes.

      Fix for bad error pointer deleting non existent sprite · 431bcb1a
      Robert Sprowson authored
      Doing *WimpKillSprite _not_there_  had the following behaviour
      
      Priority   | Sprite exists  Sprite doesn't  Sprite is ROM
      Lo then Hi | Deletes        Bad error ptr   Silence
      Hi then Lo | Deletes        Silence         Silence
      
      The bad error pointer was caused by an early return if the high priority pool is the ROM sprites (because the earlier failure to find it in the low priority pools set V, and the early return used TEQ, so the error pointer in R0 was the SpriteOp reason code).
      Proceed to try to look up the sprite, even if there's no hope of deleting it, in order to get a valid error message.

      Fix crashes when a Wimp_Poll post-filter causes the Wimp to postpone switching to a VFP-enabled task
      
      Detail:
        s/Wimp07 - In ExitPoll, swap around the order of restoring the FP context and calling the poll post-filter so that the FP context is restored after the post-poll filter has been invoked. Previously, the VFP(+FPA) context would be restored, then the post-poll filter would be invoked. If the post-poll filter was claimed, the Wimp would then scan the pollwords again and most likely decide to switch to a different task. The appslot will then be switched over, and ExitPoll will be invoked again, attempting to restore the VFP/FPA context for that task - potentially causing a crash or other bad things because the VFP context used by the original choice of task is no longer paged in. For FPA this was never really a problem, since the context is stored in the RMA rather than being potentially stored in appspace.
        s/Wimp03 - Add some extra debug out for tracking VFP context management

      Recache currentmode at the right time · 121acd27
      ROOL authored
      Detail:
        Modification to make the Wimp reread 'currentmode' by calling OS_ReadSysInfo 1 in the following circumstances
        1. On module init (accounts for being softloaded off disc)
        2. At Service_Reset (accounts for any graphics driver starting after it in ROM module order)
        3. When Service_ModeFileChange (new, this catches the new mode selected by an MDF or EDID during !Boot)
        Commoned up these 3 cases into 1 function.
        This restores the design intent that to get the monitor's native resolution it is *not* required to configure the MonitorType=EDID, indeed doing so wouldn't have helped loading EDID off disc if the monitor's data is found to be incorrect and needing overriding.

      Reinstate Wimp_ClaimFreeMemory · 503570de
      Jeffrey Lee authored
      Detail:
        This restores support for Wimp_ClaimFreeMemory, via having the Wimp manage a small-ish (4MB) DA that is used to satisfy Wimp_ClaimFreeMemory requests. The Wimp will only ever grow the DA, but the DA is shrinkable, so the system should shrink it as necessary should the free pool run too low.
        Options/s/!Default, Options/s/32, Options/s/Ursula - Add DynamicAreaWCF option to control support for the Wimp_ClaimFreeMemory DA. Enable the option for any builds of the module destined for RISC OS 5.
        Options/s/!Debug - New debug option for Wimp_ClaimFreeMemory debugging (mainly DynamicAreaWCF code path)
        Wimp/s/Wimp01 - Add calls to create/destroy DA on startup/shutdown
        Wimp/s/Wimp08s - DA create/destroy implementation. DA is only used if the free pool is a PMP or the Wimp expects kernel free pool locking but the kernel doesn't support it. Modify Wimp_ClaimFreeMemory to use the DA if it's present.
