* Add scaling for vfnts and scale multipler to gr_string
* nullptr
* Add scaling to a couple other string operations
* Add scaling features to additional bitmap drawing methods
* Implement framework for rendering hud gauges in config mode
* fix merge error
* address feedback
1. fix a bug where blips expired immediately every frame; they now track their expiration by object
3. store object numbers rather than object pointers
3. clamp both the high bound and the low bound of alpha values
Convert `sweep_duration` from seconds to milliseconds to work correctly with the timestamp system. Also clarify use of `game_get_overall_frametime()`, especially with `ba.getFrametimeOverall()`; and add `ba.getSecondsOverall()` to do what `ba.getFrametimeOverall()` allegedly did.
This is similar to the other changes I already posted. Here the sound
instance handles are converted to their own handle type which will make
it easier to use the sound API.
This adds a new class which allows to create type safe resource handle
types. At the moment, the engine uses ints pretty much everywhere for
providing handles to resources created by the specific subsystems. Since
all ints are the same to the C/C++ typesystem it is perfectly legal to
pass a sound handle to the graphics API as a buffer handle which will
obviously cause issues.
This adds a new type called "ID" which is a wrapper class for a generic
handle but with added type safety. An instance of this class cannot be
passed to a function expecting another type of handle which provided
compile-time type safety for these APIs.
As an initial test I converted the game sound handles to this new type.
I already found a bug in the mainhall system thanks to this new type.
The mainhall used the game sound handles as sound instance handles which
probably meant that that specific code never really worked right. I
removed the code since there was no better alternative for fixing it.
All transformations are now handled by shaders so there is nothing
special going on in the graphics API specific code anymore. Since model
uniform buffers require access to these matrices I moved the matrix
handling out of the graphics API code.
The DRADIS has two icon types, one where the color is scaled with the
IFF color and once which isn't. Due to a regression, both icons were
previously scaled with the IFF color which made the icons look bad. This
fixes that.
This introduces a new mechanism for handling bit flags. Instead of using an int (or two, or three) to write bits into, this uses the std::bitset in a wrapper class that accepts an enum class as input. This means that certain classes of errors we've had a few of in the engine, where a coder used the wrong set of flags or checked them against the wrong variable (SF_STEALTH vs SIF_STEALTH, for example) can now be detected at a compiler level rather than not at all.
This allows to use standard TrueType Fonts for text rendering in FSO. It uses the NanoVG library which provides the ability of drawing 2D shapes. This library is used for most 2D operations now and can also be used directly by using the PathRenderer class.
